The nominative form of 積もる (つもる, tsumoru, “to intend”).
つもり • (tsumori)
- 積もり: intention, purpose, plan
- Iku tsumori da.
- I intend to go.
- Watashi wa kare ni denwa suru tsumori da.
- I'm going to call him.
- 積もり: conviction, belief
- This word is usually written using hiragana alone (つもり) instead of kanji (積もり), as it is grammaticalized – compare みる (miru) (from 見る) and others.
- つもり cannot be used as a nominal – 「つもりは…」 (“The plan is…”) is incorrect. It is rather a suffix, 〜つもり.
- For a nominal meaning “plan”, 企画 (keikaku) or other such words are used instead.
- 〜つもり has a different meaning when it follows a verb that is in the present-future (non-past, imperfective) tense – in which case it means “plan, intention” – and when it modifies either a verb in the past (perfective) tense, or an adjective, or a noun followed by 〜の – in which case it means “conviction, belief, impression, understanding”.
- This latter usage is less-taught in textbooks; see Rubin reference for extended discussion. A humorous example use is, if asked 「アメリカの方ですか？」 (“Are you American?”) – and one in fact is – to reply 「アメリカ人のつもりですけど…」 (“Well, I was the last time I looked…”, literally “I believe that I am an American [but I’m not completely sure]”).
