Reference
Common spoken reductions, clipped endings, and casual equivalents that show up in manga, anime, and everyday dialogue. Some entries are colloquial counterparts rather than strict one-to-one textbook substitutions.
| Casual form | Standard form | Example | Explanation |
|---|---|---|---|
| って | と / とは | 行くって言った"He said he's going." | The casual way of reporting speech or attributing a statement to someone. Also used to mark a topic being defined or questioned. |
| なんて | などと / なんと | なんていっても無駄だよ"No matter what you say, it's pointless." | A flexible casual form used for quoting, downplaying, or reacting with surprise or disbelief. Depending on context it may line up with などと, なんと, or the dismissive "the very idea of ~", so it is not a one-to-one substitute for a single standard form. |
| ったら | と言ったら | もう、あなたったら!"Honestly, you're something else!" | Often follows a person's name or pronoun to signal exasperation, teasing, or affectionate frustration. It keeps the flavor of と言ったら but sounds much more conversational. |
| てゆーか てか |
というか | てか、それ違くない?"I mean, isn't that wrong?" | Used to pivot, correct, or reframe what was just said. Closer to "actually" or "I mean" than a direct translation. Very common in young, casual speech. |
| Casual form | Standard form | Example | Explanation |
|---|---|---|---|
| 〜てる 〜でる |
〜ている 〜でいる |
まだ食べてる"He's still eating." | The い of いる is swallowed almost universally in casual speech. Covers both ongoing actions and states resulting from a past event. |
| 〜とく 〜どく |
〜ておく 〜でおく |
先に買っとく"I'll buy it ahead of time." | A contraction of ておく / でおく, which expresses doing something in preparation for later. The お of おく is dropped and the remainder attaches directly to the て-form. |
|
〜ちゃう 〜じゃう |
〜てしまう 〜でしまう |
全部食べちゃった"I went and ate it all." | Marks an action as fully completed, often with a sense of unintended consequence, mild regret, or surprise. Past form is ちゃった. |
| 〜なきゃ | 〜なければ(ならない) | もう行かなきゃ"I have to go now." | Compressed from なければ, and in obligation patterns it usually stands in for なければならない or なければいけない. In speech the rest of the obligation phrase is often left unspoken. |
| 〜なくちゃ | 〜なくてはいけない | やらなくちゃいけない"I've got to do it." | Another obligation contraction, slightly softer in feel than なきゃ. The いけない is often dropped too, leaving just なくちゃ. |
| 〜とこ | 〜ところ | 今やるとこだよ"I'm just about to do it." | ところ contracts to とこ in casual speech whether used as a physical noun ("place") or in grammatical constructions indicating timing. |
|
〜ちまう 〜じまう |
〜てしまう 〜でしまう |
財布なくしちまった"I went and lost my wallet." | A rougher, more characterful contraction than ちゃう / じゃう. Common in manga and anime dialogue, often with a blunt or masculine voice. |
| Casual form | Standard form | Example | Explanation |
|---|---|---|---|
| じゃ | では | それじゃダメだよ"That won't do." | The standard negative and conditional connector では becomes じゃ in virtually all casual contexts. Look for it before ない, ダメ, and なくて. |
| だろ | だろう | そうだろ?"That's how it is, right?" | Used to seek agreement or float a conjecture. The trailing う is often dropped in casual speech; sentence-final だろ can sound blunt or masculine depending on tone, while でしょ is a softer alternative many speakers prefer. |
| じゃん | ではないか / じゃないか | これ、便利じゃん"Hey, this is pretty handy." | A casual contraction used to point out something obvious, seek agreement, or add a light "see?" nuance. It is not simply a plain negative; intonation and context do a lot of the work. |
| Casual form | Standard form | Example | Explanation |
|---|---|---|---|
| 〜けど | 〜けれど(も) | 行きたいけど、無理"I want to go, but it's impossible." | The everyday contrastive connector. けど is near-universal in casual speech and feels lighter and more conversational than けれど(も). |
| んで | ので | 遅れるんで先に行って"I'll be late, so go on ahead." | A casual reduction of ので. Connects a reason to a result, with a softer feel than から. The の contracts to ん and the full form collapses to んで in casual spoken Japanese. |
|
ん / んだ んです |
のだ / のです | そうなんだ"Oh, so that's how it is." | One of the most frequent patterns in casual Japanese. Adds an explanatory or assertive nuance — the speaker is either offering a reason or reacting to new information. |
| 〜ちゃ 〜じゃ |
〜ては / 〜では | 行っちゃダメだよ"You mustn't go." | Contractions of ては and では respectively. Used in conditional patterns where the implication is that doing something is problematic or prohibited. ては contracts to ちゃ after most verbs; では contracts to じゃ. |
| Casual form | Standard form | Example | Explanation |
|---|---|---|---|
| わかんない | わからない | そんなのわかんないよ"I don't know that." | A very common spoken reduction of わからない. In fast casual speech the ら drops and the rest tightens to んない, which is often reflected in informal writing too. |
|
すごっ やばっ かわいっ |
すごい やばい かわいい |
すごっ、なにそれ!"Whoa, what is that!" | い-adjectives clipped of their final い for exclamatory effect. The abrupt cutoff itself conveys the force of the reaction — it's a stylistic intensifier, not just laziness. |
| ほんと | ほんとう | ほんと?信じられない"Really? I can't believe it." | Final う is routinely dropped in casual speech. ほんとう is the full form but ほんと is so prevalent it barely registers as a contraction. |
| ありがと | ありがとう | ありがと、助かった!"Thanks, you're a lifesaver!" | The same final う drop as ほんと. Entirely standard in casual contexts — using the full ありがとう can sound stiff or overly formal between friends. |
| 〜ないで | 〜ないでください | 泣かないでよ"Please don't cry." | Not so much a sound contraction as a casual shortening of the request pattern 〜ないでください. Dropping ください removes politeness and makes the request feel more personal or direct. |
| Casual form | Standard form | Example | Explanation |
|---|---|---|---|
| 〜ねえ 〜ねぇ |
〜ない | そんなの知らねえよ"I don't know anything about that." | A rough vowel-shifted negative common in manga, anime, and blunt spoken Japanese. Frequently reads as tougher or more masculine than the plain ない form. |
|
じゃねえ じゃねぇ |
じゃない | 俺のせいじゃねえ"It's not my fault." | The rough counterpart of じゃない. Very common in confrontational or masculine dialogue, and easy to confuse with entirely different words if you have not seen the pattern before. |
| 〜てえ 〜てぇ |
〜たい | 早く帰りてえ"I wanna go home already." | A rough or emotionally charged version of the desire form たい. Often used when a character is frustrated, determined, or speaking in a very unfiltered voice. |
|
すげえ うめえ やべえ |
すごい うまい やばい |
この店、マジでうめえな"This place is seriously good." | Highly common vowel-shifted forms in rough casual speech. Not every adjective shifts this way, but these particular ones appear constantly in manga-style dialogue. |
|
〜りゃ 〜けりゃ |
〜れば 〜ければ |
見りゃわかるだろ"You'd know if you looked." | A clipped conditional meaning "if" or "when." Very common in compressed spoken lines like ありゃ, なけりゃ, or やりゃ, especially in terse male dialogue. |
| そりゃ こりゃ |
それは これは |
そりゃ無理だ"Well, that's impossible." | Frequent spoken contractions that often appear at the start of a reaction or judgment. They can feel throwaway in English, but in Japanese they are common rhythm-setting openings in dialogue. |
| 〜っす | 〜です | 了解っす"Got it." | A slurred, youth-coded version of です. Often signals a junior, sporty, delinquent, or overly casual-polite character voice rather than plain neutral politeness. |
