Usage

Neutral in register and common in everyday conversation and writing. It typically describes emotions, desires, or bodily sensations that arise on their own, such as longing, sleepiness, or worry. It is less colloquial than てしょうがない and less formal than てならない.

Watch out

Note that it mainly describes the speaker's own feelings; for others, ようだ or らしい are common, though narration or clear context allows direct statements.

Do not use くて with な形容詞; use で instead, as in 心配でしかたがない.

Learners should use it for spontaneous feelings or sensations, not for deliberate actions the speaker controls.

Easily confused with
  • てしょうがないN3「てしょうがない」 has essentially the same meaning and attaches to the same forms as this pattern, and can be used for both psychological feelings and physical sensations, so the two are generally interchangeable. The difference is that it is more colloquial, appearing mostly in everyday conversation, and it can also be said as 「てしようがない」.
  • てたまらないN2「てたまらない」 has essentially the same meaning and attaches to the same forms, and the two are interchangeable in most cases. It emphasizes a feeling so intense it is hard to endure, and is especially natural for physical sensations like pain, heat, or cold; 「〜てしかたがない」 instead focuses on something uncontrollable and continuing as it is.
  • てならないN2「てならない」 is similar in meaning, and the two are often interchangeable when expressing strong emotions; however, it is more literary and understated, used mainly in writing, and it frequently attaches to spontaneous verbs like 「思われる」 and 「気がする」 to mean 'can't help but...'.
  • てかなわないN1「てかなわない」 is used mainly for negative things, complaining that something is 'unbearable', and is often said about weather, noise, work burdens, and the like; it is colloquial and rarely used for positive feelings. When expressing discomfort such as sleepiness, pain, or heat, the two are mostly interchangeable.
  • てやまないN3「てやまない」 is used in formal writing and speeches, attaches only to verbs, and solemnly expresses long-lasting wishes or respect; it is not used for sensations like pain or sleepiness. When stating a third person's attitude, it also does not require adding 「ようだ」 or 「らしい」.

てしょうがない is a more colloquial version with the same meaning, and てたまらない stresses that the feeling is unbearable. てならない is more written and often used with spontaneous feelings (気がしてならない). てかなわない expresses annoyance at something hard to put up with. てやまない is formal and expresses a sincere, lasting wish or feeling rather than a sensation.
