～みたい (Casual): "Like" and "Seems Like" in Japanese

～みたい has two readings in casual Japanese: direct comparison ("X is like Y") and evidential inference, where the speaker judges from evidence ("it seems like X").¹² It is the everyday-speech counterpart of the more formal ようだ. Despite its sentence-final position, it conjugates as a な-adjective.²³

Overview

What ～みたい means

～みたい is a suffix that attaches to nouns, plain-form verbs, plain-form い-adjectives, and な-adjective stems. Depending on context, it does one of two related jobs.¹²⁴

The first job is direct comparison: the speaker likens A to B, with no guessing involved. JMdict captures this sense as "-like, sort of, similar to, resembling."⁵

The second job is evidential inference: the speaker draws a conclusion based on what they have personally observed or felt. JMdict glosses this sense as "seems / appears to be."⁵

The split is grammatical, not lexical. The same form does both jobs. Context and the host word's category tell you which reading is intended.⁴⁶

Register and JLPT placement

～みたい is JLPT N4-level grammar and clearly casual.⁷²⁶⁸ JMdict tags the suffix as colloquial (口語, everyday spoken language).⁵

Tae Kim puts the register caveat plainly: ～みたい "is really a grammar only used in conversation. Do not use it in essays."⁷ Wasabi makes the pairing explicit: "ようだ is a formal word and preferred in writing, while みたいだ is a casual word and preferred in speech."⁶

ようだ is the formal counterpart of ～みたい in the same meaning slot. The two share meaning. They differ in register and in one piece of morphology, the noun connector, covered in the next section.¹²⁶

The 見たい trap

The grammatical ～みたい is normally written in hiragana. The kanji spelling 見たい is the desiderative form of 見る ("want to see") and has nothing to do with this grammar point.⁷³

Never write the modal as 見たい

Writing the grammar in kanji as 見たい collides with the unrelated desiderative ("want to see") and is read as the verb, not the modal. Keep the modal in hiragana: 雨が降るみたい, not 雨が降る見たい.⁷³

The history explains the spelling. ～みたい is historically a contraction of 見た (mita, "having seen") + よう (yō, "as if / as though"). The kana spelling keeps a visible distinction between the literal verb and the grammaticalized modal that grew out of it.³

Formation: how ～みたい attaches

The host word's part of speech determines the attachment rule. The main case to remember is the noun rule: there is no copula between the noun and みたい. The other three categories use the plain form (verbs and い-adjectives) or the bare stem (な-adjectives).

Attaching to nouns (no だ between)

Noun + みたい. No copula だ is inserted between them.¹²⁶⁹

This is the most important formation rule. It is also the key contrast with ようだ, which requires の after a noun (noun + の + ようだ). Wasabi's minimal pair makes the contrast visible: あの人は警察みたい (casual) versus あの人は警察のような (formal).⁶¹⁰

彼かれは子供こどもみたいだ。⁴
"He's like a child."

夢ゆめみたいだ。¹¹
"It's like a dream."

外そとは、夏なつみたいだよ。¹¹
"It's like summer outside."

あの人ひとは、日本人にほんじんみたいですね。¹¹
"That person seems Japanese, doesn't she."

Attaching to verbs (plain form)

Plain-form verb + みたい. Plain affirmative, plain negative, and plain past forms all attach directly. No particle or copula comes between them.¹²¹¹⁴

彼かれは少すこし疲つかれてるみたいだ。¹¹
"He looks a little tired."

どうやら食たべすぎたみたいだ。¹¹⁵
"Looks like I ate too much."

何なにか事故じこがあったみたいだ。¹¹
"It seems there's been some kind of accident."

Attaching to い-adjectives (plain form)

Plain-form い-adjective + みたい. The same plain-form rule as verbs applies. Plain negatives like 高くない and 寒くない attach directly.²¹¹⁹

このパソコンは壊こわれているみたいだ。¹¹
"It looks like this computer is broken."

彼女かのじょはあの猫ねこがかわいくないみたいだ。⁴
"She doesn't seem to find that cat cute."

Attaching to な-adjectives (drop な, no だ)

な-adjective stem + みたい. The な does not appear, and no copula is inserted. This pattern mirrors the noun rule.²⁴⁹

静しずかみたいだ。⁴
"It seems quiet."

Conjugation: ～みたい as a な-adjective

～みたい itself inflects on the な-adjective pattern. Tae Kim states it directly: ～みたい "conjugates like a noun or na-adjective and not an i-adjective."⁷ Bunpro agrees: both ～みたい and ようだ "function grammatically as な-adjectives."² Wiktionary lists the full paradigm (attributive みたいな, adverbial みたいに, past みたいだった, negative みたいではない), and JMdict tags the entry as a な-adjective.³⁵

Why this matters for learners

Once you see みたい as a な-adjective stem, every inflected form follows patterns you already know. The negative, past, attributive, and adverbial forms are not new grammar. They are the same conjugation table applied to a new stem.⁷²³

Affirmative present: ～みたい / ～みたいだ / ～みたいです

Three registers share one meaning:

• Bare ～みたい, no copula: default casual register in everyday speech.⁷⁴
• ～みたいだ: plain style with an overt copula.¹¹¹³
• ～みたいです: polite style.¹¹

Negative: ～みたいじゃない

To form the negative, treat みたい as the な-adjective stem and apply the standard な-adjective negative.⁷³ The contracted casual form is ～みたいじゃない; the longer form is ～みたいではない.⁷³ Polite equivalents follow the regular な-adjective polite negative: ～みたいじゃないです / ～みたいではありません.³

このピザはお好このみ焼やきみたいじゃない？⁷
"Doesn't this pizza look like okonomiyaki?"

Past: ～みたいだった

Past affirmative follows the standard な-adjective past inflection. The polite form is ～みたいでした.³

私わたしはその時とき、まるで大人おとなになったみたいだった。¹¹
"At that moment I felt just like I'd become an adult."

Negative past: ～みたいじゃなかった

Past negative combines the negative and past inflections above: みたいじゃない (negative) → みたいじゃなかった (negative past). The polite forms are ～みたいじゃなかったです / ～みたいではありませんでした.³

Attributive ～みたいな + noun

When ～みたい modifies a following noun, it appears as みたいな, the standard な-adjective attributive ending.⁷²¹²³ The な appears only in attributive position; it never appears sentence-finally.¹²³

モデルみたいな女性じょせい。⁶
"A woman like a model."

先生せんせいみたいな小ちいさくてかわいい先生せんせいは今いままでいませんでしたね。⁴
"We have never had a teacher this small and cute before."

Adverbial ～みたいに + verb / adjective

When ～みたい modifies a following verb or adjective, it appears as みたいに, the standard な-adjective adverbial ending.^7212133 Bunpro notes that the modified predicate does not have to be the immediately next word.¹²

彼女かのじょの心こころは氷こおりみたいに冷つめたい。¹³
"Her heart is as cold as ice."

私わたしはお母かあさんみたいになりたい。¹³
"I want to be like my mom."

子こどもみたいに遊あそんだ。¹³
"I played like a kid."

Nuance and usage contexts

Reading 1: direct comparison ("is like X")

In the comparison reading, noun + みたい marks a similarity or resemblance. The speaker is not guessing. They are likening A to B.¹⁴⁶⁵ JMdict captures this sense as "-like, sort of, similar to, resembling."⁵ It is common in compliments, exaggeration, and set phrases.⁴⁶¹⁴

彼女かのじょはスポーツ選手せんしゅみたいです。⁶
"She's like an athlete."

あなたみたいに美うつくしい人ひとは初はじめてだ。¹³
"I've never met anyone as beautiful as you."

Reading 2: evidential inference ("seems like X")

In the inference reading, verb / adjective / noun + みたい marks a conjecture based on what the speaker has directly observed or felt: wet streets, fatigue, a stomach feeling.¹²¹¹⁴ Bunpro describes the evidence type as "direct, reliable information."²

This evidence source is what separates ～みたい from らしい: ～みたい is the speaker's own observation, while らしい is information that came from outside.²⁴⁶

何なにとなく雨あめみたいだ。¹¹
"Looks like rain."

台風たいふうで電車でんしゃが止とまっているみたいだ。⁴
"Looks like the trains are stopped because of the typhoon."

Casual register and where みたい fits in conversation

～みたい is the default for chatting with friends, texting, and internal monologue. In the same role, ようだ sounds bookish or like a news report.⁷²⁴⁶

Wasabi puts the split plainly: "ようだ is a formal word and preferred in writing, while みたいだ is a casual word and preferred in speech."⁶

In casual conversation, sentence-final みたい often stands alone with no copula at all (no だ, no です). This is the default casual register, not a mistake.⁷⁴

Trailing-off みたいな…

Maggie Sensei notes a further colloquial pattern of trailing off mid-sentence with ～みたいな…, used to convey vagueness or to soften a statement: なんか、お腹減った、みたいな… ("I'm kind of hungry, like…").⁴

Set phrases and idiomatic uses

A small group of noun + みたい combinations work like idioms and are best learned as units. JMdict registers 馬鹿みたい / バカみたい as its own headword, tagged as a な-adjective and usually written in kana.¹⁴

• 夢みたい: "like a dream, dreamlike." JLPT Sensei's lead example sentence is the bare 夢みたいだ.¹¹³
• 嘘みたい: "unbelievable, like a lie," used to express disbelief.⁴⁶
• バカみたい: "ridiculous, idiotic, absurd"; can soften an insult by framing the target as looking foolish rather than being foolish.¹⁴
• 子供みたい: "childlike, childish"; can be either a compliment or a complaint depending on context.¹³⁴

夢ゆめみたいだ。¹¹
"It's like a dream."

バカみたいに見みえるのは分わかってる。¹³
"I know I look like an idiot."

～みたい on the modal-suffix map

～みたい sits in a four-way map with ようだ, らしい, and そうだ. Each suffix marks a slightly different evidence type or register. Use the map below as a navigation aid. Deeper comparisons are in the dedicated articles for the formal counterparts.

vs. ようだ (formal counterpart)

ようだ shares both readings, comparison and inference, with ～みたい. The two differ in register and in one piece of morphology: after a noun, ようだ requires の (noun + のようだ), while ～みたい attaches directly (noun + みたい).¹²⁶¹⁰

Both inflect on the な-adjective pattern. ようだ has attributive ような and adverbial ように; ～みたい has みたいな and みたいに.²³ The Dictionary of Intermediate Japanese Grammar's entry for mitai da treats it as the colloquial counterpart of yoo da and lists the noun-direct, plain-form, and な-adjective-stem attachments.¹

vs. らしい (external evidence, hearsay)

らしい marks information that came from outside the speaker, such as something heard, read, or reported. ～みたい marks the speaker's own observation or impression.²⁴⁶

The rain test case makes the split concrete. 雨が降ったらしい reports "apparently it rained" (someone told the speaker), while 雨が降ったみたい reports "looks like it rained" (the speaker sees wet streets).²⁶

vs. そうだ (visual "looks-like" and hearsay)

The そう suffix has two distinct grammars. The looks-like form attaches to い-adjective / な-adjective / verb stems and marks an immediate visual impression: おいしそう, "looks delicious."⁴⁶ The hearsay form attaches to the plain form and marks reported information, much like a less casual らしい.⁶

～みたい overlaps with both そう grammars, but it is broader because it accepts all parts of speech, and it is more casual.²⁴⁶

Quick decision cue

Cue	Pick
"I personally noticed"	みたい24
"I was told / I read"	らしい or そう-hearsay46
"It visually looks delicious"	そう-looks-like6
"I'm writing this in a report"	ようだ76

Good to know

～みたい is a contraction of 見た + よう

The grammatical ～みたい developed from 見た (mita, "having seen") + よう (yō, "as if / as though"). The contraction appeared from the middle of the Meiji period and grammaticalized into a single modal suffix.³

The history explains two surface facts at once. The hiragana convention preserves a visible split from the kanji 見, which now belongs only to the literal verb 見る. The な-adjective inflection is inherited from ようだ, which the suffix grew out of.³

Inserting だ between a noun and みたい

A common beginner error is to put the copula だ between a noun and ～みたい, by analogy with sentences like 学生だ. The wrong form looks like 子供だみたい, intended to mean "He's like a child" or "He seems like a child."

The correct form drops the copula entirely:

子供こどもみたい。⁴⁶
"Like a child."

～みたい attaches directly to a noun with nothing between them. This is the key rule that distinguishes it from the formal ようだ counterpart, which requires の (子供のようだ).⁶¹⁰

Writing the modal in kanji as 見たい

Writing the grammatical modal in kanji as 見たい collides with the unrelated desiderative form of 見る ("want to see"). A learner who writes 雨が降る見たい means "Looks like it's going to rain," but produces a string that reads as "want to see the rain falling."

The correct spelling keeps the modal in hiragana:

雨あめが降ふるみたい。⁷³
"Looks like it's going to rain."

～みたい in formal writing

In formal essays, news reports, and business writing, shift from ～みたい to ようだ. Tae Kim is blunt on this point: ～みたい "is really a grammar only used in conversation. Do not use it in essays."⁷ Wasabi echoes the same line, pairing ようだ with writing and みたいだ with speech.⁶

The dropped だ in casual speech

In conversation, sentence-final ～みたい often stands alone with no copula at all (no だ, no です). This is the default casual register, not a mistake:

もう売うり切きれみたい。⁷
"Looks like it's sold out already."

Maggie Sensei also documents the colloquial pattern of trailing off mid-utterance with ～みたいな…, used to soften a statement or convey vagueness.⁴

Why ～みたい is not a desiderative

Despite ending in ～たい, ～みたい does not mean "want to." The clearest giveaway is its attachment behavior: it attaches to nouns directly, which the desiderative ～たい cannot do. Compare 子供みたい (grammatical: "like a child") with the impossible 子供たい. The desiderative is built only from verb stems.⁷³

Memorize the set phrases as units

夢みたい, 嘘みたい, バカみたい, and 子供みたい cluster as idiomatic adjectives. JMdict even gives バカみたい its own headword as a な-adjective.¹¹⁴¹⁴ Treating these as units saves the learner from re-deriving the comparison from scratch every time the phrase appears.
