expression, i-adjective
Used to describe something so exceptional that nothing else compares. Often modifies nouns like 成功, 才能, or 美しさ.
彼は類のない才能を持っている。
He has unparalleled talent.
これは類のない成功だ。
This is an unprecedented success.
前例のない also means 'unprecedented', but focuses on the lack of a prior example or precedent, while 類のない emphasizes that nothing of the same kind exists.
比類のない is a more formal synonym with the same meaning; 類のない is slightly more common in everyday speech.
Phrase consisting of 類 (kind, type) + の (possessive particle) + ない (not exist). Literally 'there is no kind/equal'.
