だけOnly / just
だけ limits or restricts scope. Attaches to nouns, verbs, and counters to mean 'only that much' or 'just'. Unlike しか (which requires negative verb), だけ can be used with both positive and negative sentences.
Common mistakes
- Confusing だけ with しか — しか requires a negative verb, だけ does not
- Placing だけ in the wrong position — it follows the word it restricts
