An Intensity You Can't Do Anything About
てしょうがない says a feeling or sensation is so strong it is beyond managing.
- 眠くてしょうがない。(I'm unbearably sleepy.)
It attaches to states and feelings, not deliberate actions. ×走ってしょうがない is wrong — running is something you choose.
しょうがない vs しかたがない
Identical in meaning. しかたがない is the written form; しょうがない is the spoken contraction and much commoner in conversation.
On Its Own — Resignation
Standing alone, しょうがない means "it can't be helped" — the standard Japanese response to something unfortunate and unfixable:
- 雨だからしょうがないね。(It's raining, so nothing to be done.)
This use is extremely frequent and worth knowing as a unit.
Against てたまらない and すぎる
| Pattern | Sense |
|---|---|
| てしょうがない | so much I can't cope — spoken |
| てたまらない | so much I can't bear it — slightly more literary |
| すぎる | excessively — a judgement about degree, not a feeling |
すぎる can criticise anything; てしょうがない reports how something feels to you.
ても始まらない
The related ても始まらない means "there's no point even doing it": 心配しても始まらない (worrying won't get us anywhere).
