What does ～だけ mean? Japanese grammar N4

Forming it

How to use it

Limiting a scope, stating a fact in a neutral way.

• だけ limits scope and goes with an ordinary AFFIRMATIVE ending: 一人だけ来ました (only one person came).
• NEUTRAL nuance — it just states a fact, neither praising nor criticizing. This is the one but crucial difference from しか～ない (always negative, "too little"). Same event: 「五分だけ待ちます」(I'll wait just 5 minutes — that's my decision) vs 「五分しか待てません」(I can only wait 5 minutes — not enough, impatient).
• だけ keeps most particles and stands BEFORE them: 「これだけが必要です」・「田中さんにだけ話しました」. As for を, it's usually placed after だけ: 「これだけを見てください」, but dropping を is also natural.
• With verbs, だけ creates the meaning "only doing ~": 「見るだけです」(just looking, not buying). This is an extremely common sentence when entering a shop.

Examples

• パーティーには三(さん)人(にん)だけ来(き)ました。

  Only three people came to the party.

• すみません、見(み)るだけです。

  Sorry, I'm just looking.

• この店(みせ)は日曜日(にちようび)だけ休(やす)みです。

  This shop is closed only on Sundays.

Keep in mind

• だけで = "just with ~ already": 見るだけで嬉しくなります (just looking at it already makes me happy).
• To express "not only ~ but also", use だけでなく (~だけじゃなくて in spoken language).

Common mistakes

• Wrong一(ひと)人(り)がだけ来(き)ました。

  Only one person came.

  Correct一(ひと)人(り)だけ来(き)ました。

  だけ must stand RIGHT AFTER the noun, before が／を (「一人だけが」), it cannot be reordered as 「一人がだけ」 — wrong particle order.

• Wrong財布(さいふ)に五(ご)百(ひゃく)円(えん)だけあって、何(なに)も買(か)えません。

  There's only 500 yen in the wallet, so I can't buy anything.

  Correct財布(さいふ)に五(ご)百(ひゃく)円(えん)しかなくて、何(なに)も買(か)えません。

  だけ carries a neutral nuance, not implying "too little, not enough." But the sentence continues with "can't buy anything" (implying not enough money) — contradicting だけ. To express "too little, not enough," use しか～ない.

Exam tips

• Remember the contrasting pair: だけ + affirmative (neutral) ↔ しか + negative (regretful, too little).
