What is だけ?

だけ is a particle meaning “only” or “just”. It limits an item or action to that amount or category. It can attach to nouns, verbs, and even some adjectives.

  • Noun + だけ: コーヒーだけ (only coffee)
  • Verb (plain) + だけ: 食べるだけ (just eat)
  • Used with positive verbs. The negative "only" pattern is しか~ない.

How to Pronounce

だけ: da ke

  • Explaining limits: 一度だけ会った。

⚡ だけ vs しか:Both Mean "Only" But Different Grammar

だけ and しか both translate to "only", but しか always requires a negative verb. だけ is used with positive verbs.

Pattern Verb form Example
100円だけ Positive 100円だけある。
I have only 100 yen.
100円しか Negative 100円しかない
I have only 100 yen. (lit: nothing but)
⚠️ JLPT Trap: If the verb is positive, you must use だけ. If it's negative, しか is often the correct choice. Mixing them up is a common N5 mistake.

Common Mistakes

100円しかあります
100円だけあります / 100円しかありません
(しか requires negative!)
一つだけがない
一つしかない
(Using だけ with negative is less natural; しか~ない is emphatic)
