に及ばない — “doesn't reach the level of, no need to”

JLPT N1 Perspective & Scope

Says either that one thing falls short of another, or that an action isn't necessary

Noun + に及ばない has two related senses: comparing two things, it says one doesn't measure up to the other (“doesn't come close to X”); attached after a verb, it says an action isn't necessary — a formal cousin of までもない. Both senses share the core idea of “not reaching” some bar.

How to form it

PatternExample
Noun + に及ばない (comparison)経験では彼に及ばない — In experience, I don't come close to him
Verb + には及ばない (unnecessary)心配するには及ばない — There's no need to worry

Watch out

に及ばない's “unnecessary” sense is close to までもない, but leans more formal and often appears in polite refusals (お気遣いには及びません) — don't confuse it with the separate comparison sense (falling short); context makes clear which is meant.
