ならない — the bound element in 〜てならない and obligation patterns
ならない
Meaning
- (bound) ならない — appears in two unrelated families: 'can't help ~ing' (feeling) and 'must (not) ~' (obligation)
Key sentence
気になってならない。
I can't help being bothered by it.
Formation
| Attaches to | Form | Example |
|---|---|---|
| Spontaneous feeling: 〜て + ならない | Adj/V-て + ならない (= can't help feeling ~) | 残念でならない |
| Obligation: 〜なくては / 〜ねば + ならない | V-なくては / V-ねば + ならない (= must ~) | 行かなくてはならない / 守らねばならない |
Examples
明日までに終わらせなければならない。
I have to get it done by tomorrow. (obligation)
嫌な予感がしてならない。
I can't shake a bad feeling about this. (spontaneous feeling)
Easily confused with
〜てならない 〜てならない is the full spontaneous-feeling pattern ('can't help feeling ~'). This entry just isolates the ならない element so you can tell that family apart from the obligation one. なければならない The obligation family (なければ/なくては/ねば + ならない = 'must ~') shares the same ならない but is completely unrelated in meaning to the 'can't help' feeling use.
Notes
- ならない is rarely a word on its own — it's the tail of a larger pattern. Recognising which pattern precedes it (〜て vs 〜なくては/〜ねば) tells you whether it means 'can't help ~' or 'must ~.'
