USAGE:
A godan verb (()す → ()します). Often written in hiragana as こす since the kanji () is not in the standard-use kanji list. Primarily a cooking and craft term.

Note: The homophones ()す (to cross over) and ()す (to exceed) are completely different words.

Also used in the compound (かみ)()く (to make paper by hand), though this uses a different reading of the same kanji.

  • (ぬの)()す: to strain through cloth
