同じ

What it means

What does 同じ (onaji) mean? 同じ (onaji) is used to state that two or more items share identity or are equal in kind, quantity, quality, or state; it functions both as a modifier before a noun and as a predicate with the copula to declare equivalence between things.

Main meanings

• Equality in degree or amount (used with comparatives and quantifiers to say something is equally large, frequent, or intense).
• Similarity of manner or way when extended with forms like the construction that conveys 'in the same way' or 'similarly'.
• Pronominal use to pick out 'the same one' or 'the very same' when referring back to a previously mentioned item.
• Fixed/formal adverbial use in written registers to mean 'likewise' or 'similarly' when paired with certain endings.

How to use it

Used across casual and polite speech and in writing, 同じ (onaji) appears before nouns to modify them and after nouns with a copula to state equality; common grammatical patterns include a construction that marks two elements as equal and comparative expressions that attach degree markers to express 'as...as' or 'about the same'; in formal writing an adverbial variant conveys 'likewise', while in casual speech the copula can be dropped for brevity.
