嵩むかさむ

kasamu

to mount up · N1

嵩む (かさむ, kasamu) — to mount up — is a godan verb ending in む: かさんで (te-form), かさんだ (past), かさまない (negative), かさみます (polite).

It is usually written in kana: かさむ rather than 嵩む. It also means to pile up; to accumulate.

How かさむ conjugates · godan む-verb

Only the last kana changes: む becomes ま, み, め or も.

Which one depends on the ending. The five are one line of the hiragana chart — same consonant, vowels あ・い・う・え・お — and everything before that kana never changes.
