～かな (I wonder)

• Reading: かな
• Romaji: kana
• Formation: Verb (plain) + かな / い-Adj + かな / な-Adj / Noun + かな

Meaning

A sentence-final particle that indicates a self-addressed question or a softened question directed at others. It expresses wondering, uncertainty, or a gentle inquiry.

かな functions as an inner monologue marker when used alone, expressing the speaker's private uncertainty or contemplation. It can also serve as an indirect, softened question when addressed to someone, making a request or inquiry less direct and more polite than a straight question. The more formal variant かしら is traditionally associated with female speech, while かな is used by both genders in modern Japanese. When combined with なあ as かなあ, the wondering tone is intensified. It attaches to plain forms of verbs, adjectives, and nouns (without だ for na-adjectives and nouns).

Examples

1. 明日は晴れるかな。 I wonder if it will be sunny tomorrow.
2. この漢字の読み方は何かな。 I wonder what the reading of this kanji is.
3. もう少し安くならないかな。 I wonder if it could be a little cheaper.
