底知れぬ才能

• Reading: そこしれぬさいのう
• Romaji: soko shirenu sainō
• Kanji breakdown: 底 (bottom) + 知 (know) + れぬ (classical negative, cannot be) + 才 (talent) + 能 (ability) → talent whose bottom cannot be known
• Pronunciation: /so.ko.shi.re.nu.sa.i.nō/

Meaning

Unfathomable talent — someone whose abilities seem to have no limit or bottom.

Combines 底知れぬ (unfathomable, literally 'bottom-unknowable,' using the classical negative ぬ) with 才能 (talent). A literary-sounding compliment that suggests someone's talent is like a bottomless well — no matter how deep you look, you cannot find the end. The classical ぬ ending gives it a dramatic, almost poetic weight.

Examples

1. 新しいジャンルでも結果出すとか底知れぬ才能だよ。 Delivering results even in a new genre — that's unfathomable talent.
2. まだ伸びしろあるの？底知れぬ才能すぎる。 There's still room to grow? That talent is just unfathomable.
3. あの若さで底知れぬ才能を感じる。 At that young age, I can already sense unfathomable talent.

Do Say

Common Mistakes

• Writing 底知れない instead of 底知れぬ — both work, but ぬ gives the intended literary/dramatic feel

Origin & History
