犬いぬに論ろん語ご

expression

wasting one's breath; preaching to deaf ears

Idiomatic expression meaning that explaining something to someone who cannot understand is pointless, like reading the Analects to a dog. Often used when advice or reasoning is ignored.

• 彼かれに何なん度ど言いっても無む駄だだよ。犬いぬに論ろん語ごだ。

  No matter how many times you tell him, it's useless. It's like casting pearls before swine.

• あの頑がん固こな上じょう司しに新あたらしい提てい案あんを説せつ明めいしても、犬いぬに論ろん語ごというものだ。

  Explaining the new proposal to that stubborn boss is just a waste of breath.
