JapaneseEdit

Kanji in this term
Grade: S

Etymology 1Edit

Verb derived from noun / (kubo, an indentation, a depression) + verbalizing suffix (becoming like [noun]), with suffix ぶ mutating to む due to the preceding syllable ぼ.

VerbEdit

凹む (intransitive, godan conjugation, hiragana くぼむ, romaji kubomu)

  1. Alternative form of 窪む. To become hollow, cave in, sink in.
ConjugationEdit
Usage notesEdit

The transitive form is 凹める / 窪める (くぼめる, kubomeru). Consequently, the potential form is the same as the passive form, くぼまれる, instead of くぼめる as shown in the table above.

The spelling 窪む is used more often for くぼむ, because the alternate spelling 凹む also does double duty as へこむ.

Etymology 2Edit

Contraction of 減りこむ (へりこむ, herikomu).

VerbEdit

凹む (intransitive, godan conjugation, hiragana へこむ, romaji hekomu)

  2. To decline below a certain point; to become less.
  3. To be stuck to be at a loss: see 困る (こまる, komaru).
