Bien entendu

Ashe Dryden captures the typical reaction of someone reading this post. 

BIEN ENTENDU

Adverbial phrase. Mid-19th century.

[French, from bien well + entendu past participle of entendre hear, understand.]

Of course; that goes without saying.

It goes without saying that if something goes without saying there's no need to say it. Bien entendu? Of course. Bien entendu.
