(けたちが)

けたちがい
na-adjective, noun
on a completely different scale; orders of magnitude different
1. on a completely different scale; orders of magnitude different
Describes something that differs enormously in scale, degree, or level — literally 'different digit/column,' meaning the number of digits is different. Used to emphasize how dramatically one thing surpasses another.
(かれ)才能(さいのう)桁違(けたちが)いだ。
His talent is on a completely different level.
都会(とかい)田舎(いなか)では家賃(やちん)桁違(けたちが)いに(ちが)う。
Rent differs by orders of magnitude between the city and the countryside.

That company dominates the market with overwhelmingly superior financial power.

USAGE:
桁違(けたちが)い can be used as a na-adjective (桁違(けたちが)いな) or as an adverb (桁違(けたちが)いに). It always implies a dramatic, not slight, difference. The literal meaning relates to the (けた) (digit column) of a number being different — i.e., tens vs. thousands.

COMMON COLLOCATIONS:

  • 桁違(けたちが)いの(つよ)さ (overwhelmingly different strength)
  • 桁違(けたちが)いに(おお)い (more by orders of magnitude)
  • 桁違(けたちが)いの規模(きぼ) (on a completely different scale)

SIMILAR WORDS:
段違(だんちが)い also means "on a different level" but implies a gap of degree rather than orders of magnitude. (くら)べものにならない means "incomparable" and expresses a similar idea.
