adverb
completely; absolutely; totally; (not) at all
Used with negative expressions to mean 'not at all' or 'completely not'. The positive glosses 'completely', 'absolutely', 'totally' are possible but less common; the core usage is emphatic negation. Compare with まるっきり, which is a variant with the same meaning.

Derived from 丸 (まる, 'round, whole') + きり (from 切る, 'to cut off'), literally 'cut off completely', emphasizing totality. The exact historical development is uncertain.
