詮せん

noun

way; method; means

Refers to a way of doing something, often used in set phrases like 詮が無い (it's no use / there's no way).

• 今いまさら後こう悔かいしても詮せんが無ない。

  There's no use regretting it now.

• 彼かれに話はなしても詮せんの無ないことだ。

  Talking to him is pointless.

noun

effect; result; worth; benefit; use

  Crying won't do any good.
