This article lists down the different terms and phrases used in each episode and its definition.
Term 1: El Psy Congroo/KongrooEdit
"El Psy Kongroo" is the password that Okabe Rintaro uses whenever he ends a phone conversation pertinent to his mad endeavors. However, it is revealed that these supposed conversations he ends are simply to himself because Rintarou has his phone turned off for them. The phrase means something like "The Mind Agrees" or "The Mind is Congruous" and is supposed to be Latin, but the grammar is not correct and "El" is a definite article in several Roman languages, for example Catalan and Spanish, but not in Latin, also "congroo" in Latin is actually spelled "congruo". The phrase itself is a reference to the @channel meme "La Yohasoh Steana," and possibly something related to the real world John Titor's codeword, "Tempus edax rerum," meaning "Time, the devourer of all things." Translated as "Congroo" in the anime, the official English translation of the visual novel romanizes it as "Kongroo", which is the canon translation. Congroo is a mistranslation done with the anime -- this is supported by the video D-Mail in the final episodes coming from the e-mail address "firstname.lastname@example.org", where the initial five letters stand for Steins Gate-El Psy Kongroo"
Term 2: "Organization"Edit
This is Okabe's delusional agency involved with Committee of 300. It is supposedly a highly secret group who is sought after by many opposing organizations, whose secrets would be vital to radical change, which nobody but Okabe cares for. This is the initial irony to the series, as something initially imaginary becomes all too real.
Term 3: Metal UpaEdit
Upa is a character from the fictional anime Rai-net Kakeu. The Metal Upa is one of, if not the rarest of a collectible vending Upa figure series. While the anime is considered a child's cartoon, some collect the merchandise for their rarity.
- SPOILER* Later in the series, it is revealed that the Metal Upa is a key item in world line divergence.
- SPOILER***Also, OOPA, or OOPArt, is an acronym for "Out Of Place Artifact", a supposedly futuristic artifact found in an ancient archaeological site. The very existence of OOPArts might be evidence of time traveling that has happened before.
- Oopa is an alternative spelling for Upa. Upa is considered canon.
Term 4: AlpacamanEdit
This alpaca with a man's face is a character of virtual pet video game: a parody of SEGA Dreamcast software Seaman.
Term 5: Hououin KyoumaEdit
The main protagonist of Steins;Gate, Okabe is a self-proclaimed mad scientist and often refers to himself under the alias of Hououin Kyouma, which is also the name he uses to introduce himself to other people. Mayuri and Daru refer to him by the nickname Okarin. He also uses this alias when browsing @channel. The literal translation is "Phoenix-Shrine Madness-of-truth."
Term 6: The Choice of Steins GateEdit
This is a phrase used by Okabe to signify the meaning of events, the phrase itself, in his own occasional confession, "doesn't really mean anything."
Term 7: Futuristic Gadget #1Edit
"Future Gadget #1 Bit Particle Cannon" is one of the gadgets that Okabe and Daru made; it is nothing more than a laser gun-shaped TV remote control.
Term 8: LandlordEdit
Yuugo Tennouji, the manager of a small electronics store specializing in Braun tubes (hence, Okabe's nickname to him of "Mr. Braun") and CRT-based televisions is also the property owner of the apartment. It is shown that he does not dislike Okabe, but finds his antics to be very disruptive to the property.
Term 9: HostageEdit
(SPOILER) Explained later on in the series, Mayuri is said to be Okabe's hostage. This is because she was traumatized by her grandmother's death to the point where she would visit her grave daily during younger years. One day in 2005, Mayuri reached up towards the sky to a beam of light, and Okabe ran to hold her as he announced that he wouldn't let her go anywhere because she is his hostage—he was afraid she would be taken into the heavens and she would not be with him. It's a non-affectionate way of saying he will never have him leave her if he can help it, and he later develops the persona of Hououin Kyouma to assist in emotionally protecting her, later realizing that this is possibly detrimental to her sense of independence.
Term 10: Phone Microwave (Name Subject to Change)Edit
Future Gadget #8. This is the full name of the machine used for the initial time travel-related plot in the beginning of the series. When a message is sent to the microwave from a phone, it activates it remotely. Originally designed to be a remote-controlled microwave, this became the base concept for the time machine later on.
Term 11: Gel Banana (also Gel-bana)Edit
During experimentation with the Phone Microwave (Name Subject to Change), a banana teleports back to its stalk in a green, mushy form, marking the beginning of the time-themed plot.

Term 2: Yanagibayashi Shrine 柳林神社Edit
This is the shrine that Luka helps manage.
Term 3: Youtou SamidareEdit

In regards to Luka, talking about all his perfectly feminine qualities... but he's a guy.
Term 5: "Oh-ha~!"Edit
Short for "Ohayou-gozaimasu' (Good morning), the line is said by Amane Suzuha. The greeting won the grand prize in the buzzwords contest for 2000, a decade ago, and is significant for its horrible out-of-dateness.
Term 6: @channelEdit
This is the fictional equivalent to the textboard 2channel. The only mentioned tripcode user is JOHN_TITOR. People that use a name but no tripcode include Hououin Kyouma and 'KuriGohan and Kamehameha'. In the anime, JOHN_TITOR and Hououin Kyouma "age" the threads while KuriGohan "sages" them.

Term 9: DystopiaEdit
In reference to John Titor's time, a dystopia is a world that is put into a forced state of peace, but it's just a veiled dictatorship.
Term 10: Grandfather ParadoxEdit
The theory that if you were to go back in time to kill your biological grandfather, you would be from a parallel universe created by the death of your grandfather, as you would never have existed to begin with.
Term 11: World LineEdit
Throughout time as a linear plane, world lines are variations of reality in which details differ from one world line to the next. There is a lot of hopping of world lines, so the more times world lines are traversed, the more varied the reality is; Okabe observes how one D-Mail can change the whole nature of the city of Akihabara. The % change in variation can be tracked by the Divergence Meter, and universal events of world lines within ranges of 1% variation are tethered to outcomes governed by Attractor Fields.
Term 12: IBN5100Edit
An old computer developed by IBM, the IBN is the in-universe equivalent. It is a computer made in 1975 that runs very simple coding that is disregarded in future computer models, causing a very short stock to have ever been produced. This apparently is imperative to the use of a time machine, as said by John Titor.

Term 1: HENTAIEdit
In Japanese, means 'pervert.' Kurisu uses this quite often for Daru. He insists that he is not a pervert, but a perverted gentleman. Pervert gentleman is a @channel meme for harmless, mannerly pervert.
Term 2: Christina (Kurisu-tina)Edit
Another name given to Kurisu by Okabe. He teases her with this name because it is slightly awkward - it is a continent-neutral name of American and Japanese origin. This is because she has been studying in America, and thought that it would be more suited for his 'international conspiracy' delusions. Other conspiracy-related women include Sara, Claudia, and Simone.
Term 3: Labo-Mem (Laboratory Member)Edit
The members of the "Future Gadget Lab"; Okabe formally inducts each one personally.
Term 4: The ZombieEdit
One of the many names given to Kurisu by Okabe, due to seeing her dip her finger into a gel-bana and taste its contents for analysis. One could suggest that he enjoys teasing her. From Okabe's perspective, this name is retroactively fitting as she was, in a sense, "resurrected" after being stabbed.
Term 5: Time MachineEdit
Unlike traditional time machines, the Phone Microwave is only capable of sending a small amount of data as text back into the past; any larger object sent back would become torn apart at the molecular level (hence the gel bananas).
Term 6: Shining FingerEdit
In reference to the Kung Fu skill from the protagonist of Gundam G series, this is the nickname given to Kiryu Moeka by Okabe because of her high-speed cell phone-typing skill.
Easter egg: The voice actor of Daru had shouted "Shining Finger!" in Gundam G.
Term 7: SanboEdit

Term 8: LHC (Large Hadron Collider)Edit
This is a device used by both real-world CERN and fictional SERN to collide atoms in an attempt to create extreme forces of energy for scientific research. It's the scientific way of "knocking things together until something interesting happens," including generation of a micro-black hole. It runs underground in a ring. In Steins;Gate, the black holes it generates are used to send people and information back through time.

Term 1: Faris NyanNyanEdit
Pink haired girl, inheritant of Akiba city. She works in the same maid cafe as Mayuri and is a friend of Daru and Okarin. Daru looks up to her as the only 3D woman with a 2D soul. She often ends her sentences with the phrase(s) "Nyan-nyan" And wears cat ears (as they appear to be). These are all because of her personality of wanting to act like a cat.
Term 2: Rai-Net Dash (Rai-net Kakeru)Edit
Fictional anime series. The story of 13 episodes is introduced in the original game Steins;Gate. The story revolves around an elementary-school hero Kakeru who fights online battles against evil hackers, with his girlfriend Kirari-chan and his legendary Monster-Program called Upa.

Term 3: FireworksEdit
A device containing gunpowder and other combustible chemicals that causes a spectacular explosion when ignited, used typically for display or in celebrations.

Term 11: Singular PointEdit
A point in time and space selected for existing. Once you pass the point, the functions of time and space are switched. In other words, your time is stretched eternally and you can't escape from the point.
Term 1: Round-Table MeetingEdit
A term meaning that members of a group will equally discuss a subject as peers to solve a problem or examine as situation - their table is rectangle, so it's funny. A reference to Arthurian Legend.
Term 2: Nostalgia Drive (Nostalgic Journey that Crosses Over Time)Edit
NOSTALGIA DRIVU~ is a fancy term Okabe coined for the e-mails that they plan to send back in time. Because of his unusual naming sense, his suggestion was rejected by majority vote, and Kurisu's suggestion — D-Mail — ends up being chosen as the term to be used for subsequent experiments.
Term 3: The Mail that Leapt Through TimeEdit
This is Daru's suggestion for a name that would describe the e-mails they send back in time. The phrase is in fact a reference to the movie "The Girl Who Leapt Through Time", a story of a girl who is able to travel back in time. The movie is sad.
Term 4: D-MailEdit
Kurisu's suggestion for the term to be used for the messages they send back in time. It is a shortcut of Mayuri's suggestion "DeLorean Mail" and it eventually becomes the "official" term the Future Gadget Lab would use to pertain to the messages. DeLorean is a reference to the Back to the Future movie series, wherein the car used by the main characters is a DeLorean DMC-12.
Term 5: Operation Urd (Norn of the Past)Edit
Operation Urd pertains to the experiment which attempts to revitalize the project that involves sending messages back in time. Urd comes from the Norse Goddess of the same name who governs the past; she also has two sisters named Verthandi and Skuld. Of course, Okabe was the one who created the name.
Term 6: Kerr Black HoleEdit
This is a black hole that spins; most black holes do not have an axis, as they 'suck in' all matter and space, practically folding in on themselves (not to be confused with collapsing). A Kerr Black Hole rotates on its axis as it pulls anything, but rather than puling matter immediately into it, it can somewhat orbit matter around itself infinitely. This is why it is associated with time travel, as supposedly the more you can approach the speed of light, the slower time becomes - if you were to somehow go faster than light, time could be transversed in either direction.
Term 7: Event HorizonEdit
Basically, the "point of no return" around a black hole - nothing can escape the gravitational pull, not even light. This is the location in which nothing can affect anything outside.

Term 2: Celebrity SeventeenEdit
Kurisu is given yet another nickname by Okabe in this episode: Celeb 17 (or Celebrity 17). It pertains to Kurisu's well-to-do lifestyle (living in a hotel using her parents' money) that is unusual for someone of her age. Kurisu points out that she is eighteen, not seventeen.
Term 3: SweetsEdit
Mass media outlets like magazines, TV programs, and so on called sweet treat like cakes "sweets" in a special topic of gourmet for women in 2007 in Japan. Such a term was not popular in Japan until then. It was the buzz term used by the media. Men mocked women manipulated by the term the media made.
Term 4: Upa CushionEdit
One of the many items that can be found inside the Future Gadget Lab, the Upa Cushion is recommended by Mayuri for people who feel down or is stressed. According to her, a quick squeeze of the soft plush doll from the Rai-Net Kakeru merchandise is enough to soothe one's mind.

Term 5: Venomous RadiowaveEdit
Term 6: Pocket PagerEdit
Urushibara Luka (the guy more feminine than any woman) wants to send a D-Mail to his mother in order to change his gender, but at the time of his mother mobile phones didn't exist yet. However, there were pagers. Daru converted the message to numbers and sent it to Luka's mother using the "Phone Microwave (Name Subject to Change". The message was: "Eat vegetables for a healthy child" because Luka believed that if a pregnant woman ate a lot of vegetables, she would have a girl, and if meat - a boy.
Term 7: EatVegitablesForAHealthyChildEdit
Possibly a typographical error for "Eat vegetables for a healthy child". This was the mail sent by Urushibara Luka to her mother using Okabe's D-mail invention to change her gender (from being male to a female). However, due to it's limitations, as tested by Makise Kurisu, spaces between words have been omitted to send the full message to Luka's mother's pager (cellphones weren't so popular in the time of Luka's mother's pregnancy).
Term 8: 'Home again, home again, jiggity-jig'. Edit
In the dubbed version, Mr. Braun speaks this phrase as he steps out of the delivery truck. It is a direct reference to 'Blade Runner'; one of J. F. Sebastian's 'toys' says 'Home again, home again, jiggity-jig' when he enters his apartment.
Term 1: CosplayEdit
Cosplay is a type of performance art where participants wear costumes to represent a specific character. Mayuri's hobby is creating costumes for cosplay, and she gets excited at the opportunity to involve any of her fellow lab members. Makise Kurisu occasionally hints at her interest, as she is what many would call a 'Closet Otaku', but she is always quick to brush it off.
Term 2: Physical Time TravelEdit
Refers to the hypothetical theory of traveling time and space with the traveller's physical body. For example, Okabe, when he uses the Time Leap, travels with his mind and sends the information to the Okabe on the other world line altering the latter's memories. But if he used the methods of physical time travel (which is proven impossible in any terms) the Okabe from the original world line would vanish because his body (or to be exact, his very existence) would have already left that world line.
Term 3: Gel-OkabeEdit
Term 4: Neler (@channeler)Edit

Term 8: NakanoEdit
Term 9: 'Could you be more of a Wesley?' (Dub) Edit
Owing to Okabe's usual stubbornness, Kurisu calls him a 'Wesley'. This is a reference to Wesley Crusher from Star Trek TNG; furthermore Okabe's comments afterwords when he calls Kurisu 'Madame Next Gen' and says 'Going too boldly, I am?' at her retort, as well as calling her Nurse Chapel (who was portrayed by Majel Roddenberry, wife of Gene Wesley Roddenberry, creator of Star Trek), all pay homage to Star Trek and TNG as well. There is also a subtle hint of foreshadowing with this clever quip; Wesley was often considered infantile and annoying (like Okabe), and yet he served as a 'deux ex machina' of sorts on multiple occasions in TNG - this direct analogy belies Okabe's role as the 'savior' (as mentioned previously by John Titor).
Term 1: Bla-Chu (Blood Tune the Animation)Edit
Term 2: Mongolian blue spot (Mole)Edit

Term 9: Barrel TitorEdit
(SPOILER!) John Titor's (Suzuha's) father, which is Daru. "Barrel" is literary translated as "TARU" in Japanese. This was first noticed by Mayuri saying that "taru" sounds like "Daru" and the word barrel, meaning fat or chubby, also describes his figure.

Term 3: Pulse SignalEdit
Term 4: Time LeapEdit
A modification made to the "Phone Microwave (name subject to change)", allows Okabe to send his current memories to himself in the past without changing world lines. This is highly used and specified in the series of deaths of Mayuri, where Okabe tries to prevent her death by using the "time leap". He goes back at least three hours before the time of Mayuri's previous death but his efforts turned out to be futile. He continues to use the Time Leap in a desperate attempt to save Mayuri but ends up being unable to prevent her death countless times.

A message by an unknown member of SERN which was sent to Okabe after the development of the time leap machine. An attachment comes with the message, it is a picture of bloody beheaded doll head,
Term 1: Time Leap MachineEdit
A modification made to the "Phone Microwave (name subject to change)", allowing the user to send his current memories to himself in the past, it's not the same as the D-mail because Okabe stays in the same world line when he uses this.

Term 1: Ark RewriteEdit
Term 2: My ForkEdit
[potential spoilers] The writers of this show have a tendency to develop highly complex story-lines, and then only hint to them in the actual main story. As a way for Makise Kurisu to understand that Okabe time-leaped back a few hours prior to Mayuri's death, she tells Okabe that she needs a "fork" to go with her "spoon" in the present, so that when he time-leaps back, she'll believe that Okabe came back from the future to save Mayuri. What was revealed in one of the later visual novels is that the spoon was a gift from Makise Kurisu's father, a figure who spent much of her life psychologically abusing her. To Makise, the spoon is a way of telling herself that her father really does love her.

This is because Suzuha traveled back in the time machine that Daru tried to repair, but did not repair successfully, causing her to obtain amnesia as soon as she arrived in 1975. Hashida Suzu was the only thing she could remember, so she called herself that until she regained her memories in 2000.
Term 5: Yamanote LineEdit
One of Tokyo's most important rapid transit circuits. The circuit consists of 29 stations around the city, among them the Ginza, Shibuya, Shinjuku and Ikebukuro stations.
Term 1: Attractor FieldEdit
The invisible power that governs the events of world lines with a divergence number within 1% of universal historical changes. Despite relatively minor changes in history, every world line will obey the same destiny, such as the deaths of certain individuals at certain times, by any means. Okabe is currently trapped in a world line governed by the alpha attractor field (0%<α<1%), in which Mayuri is governed by the attractor field to die within a certain time frame. Okabe needs to cause a massively significant change in history to break the 1% divergence barrier to reach the Beta world line (1%<β<2%), in which Mayuri will not die. He was originally moved to the Alpha line through his D-Mails.

This is related to the D-mail that Kiryu Moeka sent to her past self that told her to get a new cellphone. She also sent another mail in quick succession that said, "The IBN5100 is in Yanabayashi Shrine. Recover it immediately."

Term 2: 1% BarrierEdit
Okabe needed the divergence meter to read a value greater than 1% because it would mean that he is back in the Beta world line. In the Alpha world line, it is <1% and Mayuri keeps on dying in those worlds no matter how hard Okabe tries to stop her death.
Term 3: Relativity TheoryEdit
Term 4: Operation Verthandi ("Norn of the Present")Edit

The worldline that resides between the Alpha and Beta attractor fields. Because of this, it is exempt from events that occur in either field. It's Divergence value is 1.048596%. Since it is not affected by either attractor fields, Mayuri and Kurisu do not die.
Term 3: Serious ParadoxEdit
Amane Suzuha warns Okabe that if he sees his past self, he'll cause a major time paradox. This could be related to tearing the fabrics of time and space.
Term 4: Doctor NakabachiEdit

In previous episodes, it has been revealed by Kurisu that they have a horrible relationship due to her superior intelligence and his jealousy for her. He also stole the time machine paper that Kurisu wrote in the beginning, published it under his name only, and brought it to Russia where a race to create a time machine began.
Term 5: Movie MailEdit
In the first episode, right after hiding from Kurisu, Okarin recieves a strange video message, which he can't view. In episode 23 he finds out that he can view the message after failing to rescue Makise Kurisu once. It turns out that the message was created by Okarin himself 15 years in the future.
Term 6: C204Edit
In the Beta world line, Okabe creates a time machine in 2025. It has the ability to travel both forward and backward through time. Amane Suzuha arrives in Akihabara in 2010 in this time machine. With the goal of stopping World War III, she travels back in time to recruit Okabe to save Kurisu. Okabe names this machine C204, the "C" refers to Kurisu (Christina); her death in the Beta world line and his desire to save her is the driving force behind his creation of the time machine.
This is also a reference to the "real world" John Titor, who claims that his time machine is called the C204.
Term 7: Operation Skuld ("The Goddess that Governs the Future" Operation)Edit
The operation involves Okabe seeing Makise Kurisu lying in a pool of blood, destroying the document about time machines (which Kurisu wrote), and prevent World War III, Okarin has to trick himself in thinking that Kurisu is actually dead, and he has to trick the World itself in order to save her.

Term 2: UpaEdit
Upas are those spherical toys that look like bears. They are from the fictional Rai Net Access series. Okabe bought the Metal Upa for Mayuri in the first episode of the series. This is significant because the Metal Upa was dropped by Mayuri in one of the Beta world lines and later picked it up by Makise Kurisu who placed it in the envelope with her time travel thesis. The thesis was to be stolen by Dr. Nakabachi and taken to Russia, but in the other world lines, the Metal Upa set off the metal detector, thus saving the paper from an on-board fire. By buying the Metal Upa, Okabe counterpart in the current time line bought Mayuri a Green Upa instead of a Metal Upa so that it would be picked up by Kurisu later on. Since the Green Upa is not made of metal, the metal detector wasn't set off and the thesis was burned in the plane, preventing World War III.
Term 3: Uncle's TheoryEdit
Term 4: Lab Member No.008Edit
Refers to Amane Suzuha who is going to be born 7 years after the story time line in 2017.
