意味

A structure using 何 (なん/なに) with a negative predicate to express that something does not exist at all or that there is nothing of a particular kind. It creates emphatic absence.

何～ない patterns indicate the complete absence of something, using interrogative 何 inside a negative sentence to produce a strong negation. Common forms include 何の問題もない (no problem at all), 何の変哲もない (completely ordinary), and 何一つ～ない (not a single thing). The 何の + Noun + もない pattern emphasises that there is absolutely nothing of the stated quality. This differs from a simple ない in that it proactively rules out any possibility. The pattern is versatile and appears in both formal and informal contexts. In fixed expressions like 何の得にもならない (of absolutely no benefit), it carries a dismissive or resigned tone.

例文

  3. 彼とは何の接点もない赤の他人だ。
