同(おな)じ means 'same' or 'identical.' It has unusual grammar—acting as both pre-noun adjectival and predicate.

Common patterns

  • 同(おな)じ + noun: the same ~ (同(おな)じ本(ほん))
  • 〜と同(おな)じ: same as ~ (AとBは同(おな)じだ)
  • 〜と同(おな)じように: in the same way as ~
  • 同(おな)じく: likewise, similarly (adverb)

同(おな)じ is grammatically unusual—it modifies nouns directly (like a pre-noun adjectival) but also works as a predicate (同(おな)じだ).
