Tiredness and sleep – Japanese mimetics
へとへと, くたくた, うとうと – six Japanese words for being worn out and for dozing off, with example sentences.
くたくた · to be worn out
Limpness from wear: a body, but also a thing, that has lost its firmness.
The limpness sits in the root くた (as in くたびれる, “to tire out, to wear out”), not in the voiceless く itself. The same root with the 濁点 stands in ぐったり, but what separates it from くたくた is not the diacritic — it is the shape: AっBり shows a body that has already gone slack, plain to see from outside, and it attaches with する／と, not だ／になる. Hence くたくたのシャツ and くたくたに煮る: the same word describes a worn-out thing, and へとへと is never said of a thing at all.
Examples
- 着古したシャツは襟の張りがなくなり、洗っても二度と元に戻らず、もうくたくただ。The worn-out shirt has lost the firmness in its collar and no longer comes back to shape in the wash — it is completely worn out.
- 鍋の野菜を、箸で持ち上げると崩れるほどくたくたになるまで煮込んだ。I simmered the vegetables in the pot until they went completely limp and fell apart when lifted with chopsticks.
へとへと · to be utterly drained
Exhaustion at the very end of your strength: still on your feet, but only just.
The mark exists, the pair does not: the 濁点 gives べとべと, but that is a separate word — about stickiness, not tiredness. Here the exhaustion is carried by the repeated ABAB shape itself. What is restricted is the attachment: だ and になる, never する — 彼はへとへとだった is correct, 彼はへとへとする is not. Its neighbour ぐったり speaks of a body that has already gone slack (力なく横たわる, うなだれる); as long as you are still on your feet and moving, it is へとへと, not ぐったり.
Examples
- 引っ越しを手伝って疲れ、ガス欠になったようにエネルギーが空っぽなのに、足取りは乱れず、まだ立ったまま荷ほどきを続けていて、もうへとへとだ。I helped with the move and I am so tired my energy has run down to zero like a tank out of fuel, and even so my step does not waver and I am still on my feet unpacking — utterly drained.
- 子どもを一日中追いかけて疲れ、気力が底をついたのに足元がふらつくことはなく、座る間もなく動き続けて、へとへとになった。I chased after the child all day; my last drop of energy was gone and still my legs never wavered — there was no moment to sit down and I kept moving, until I was utterly drained.
うとうと · to doze off
Sleep you keep falling out of.
The ABAB shape means “over and over” here — dozing off and waking. The AっBり shape (ぐっすり) would mean sleep slept through. すやすや speaks of even, quiet breathing, that is of sleep that lasts; うとうと of sleep that keeps breaking.
Examples
- 電車の揺れが心地よく、ゆっくり眠気が来て、夢うつつのままうとうとする。The sway of the train is so pleasant that sleep creeps up on me and I drift off half awake.
- 暖かい日差しの中、気持ちのいい眠気にゆっくり負け、何度も目を覚ましては夢うつつのままうとうとと船をこいだ。In the warm sunshine I slowly gave in to a pleasant drowsiness and kept nodding off and waking again.
すやすや · to sleep peacefully
The even, quiet breathing of a sleeper.
Voiceless す keeps the breathing even and quiet. What separates its neighbours is not a diacritic but the sleep itself: うとうと keeps breaking, ぐっすり is deep and slept right through, and すやすや says nothing about depth — which is why it fits a light sleep too, as long as the breathing stays even. The word itself lives on a verb — すやすや眠る, never すやすやする.
Examples
- 抱き上げればすぐ目を覚ますほど眠りは浅いのに、赤ちゃんは規則正しい寝息を立ててすやすやと眠っている。The baby sleeps so lightly it would wake the moment I picked it up, and yet it breathes evenly and sleeps peacefully.
- 泣き疲れた子どもは、声をかければすぐ目を覚ますほど浅い眠りのまま、寝息の間隔が乱れずすやすやと眠っていた。The child had cried itself to sleep and slept so lightly a single word would have woken it, yet its breathing kept an even rhythm and it slept peacefully.
よろよろ · to totter along
No strength left in the legs, and every step is close to a fall.
There is no voiced partner here. The dictionary describes this word in a single line — 力なく倒れそうになりながら歩くさま — and that is all of it: walking with a body that has run out of strength. Nothing about a destination; 酔ってよろよろと歩き回る is an ordinary sentence. So よろよろ is simply narrower than ふらふら: ふらふら takes the same scene and adds dizziness (熱でふらふらする) and aimless wandering (目的もなくふらふらする), where よろよろ no longer fits.
Examples
- 疲れで足に力が残っておらず、今にも倒れそうなのに、一度も休まずにゆっくりよろよろと歩いて帰った。Tiredness left no strength at all in my legs and I was about to go down at any moment, and still I did not rest even once, tottering slowly all the way home.
- 荷物の重みが肩に食い込んで足が疲れきり、一歩ずつしか進めず、それでも立ち止まらないままよろよろする。The weight of the pack digs into my shoulder, my legs are worn out and I move one step at a time — and still I do not stop, tottering along.
ぱんぱん · to be swollen tight
Legs or a belly so full they might burst.
The 半濁点 gives fullness stretched to its limit. The 濁点 form ばんばん would be banging, not a state.
Examples
- 観光で一日中歩いた疲れで、ふくらはぎがはち切れそうに張ってぱんぱんだ。After a whole day of sightseeing my calves are stretched so tight they could burst.
- 立ちっぱなしの仕事で、夕方には疲れた足がはち切れそうにぱんぱんになる。Because I am on my feet all day at work, by evening my tired legs are swollen tight.
