Passer du coq à l'âne

Meaning: To switch topics abruptly and illogically.

Literally: To jump from the rooster to the donkey

Example: “Avec lui, impossible de suivre : il passe du coq à l'âne sans arrêt.” — With him, it's impossible to keep up: he keeps jumping from one topic to another.

Origin: The phrase goes back to the 14th century: Jean Le Fèvre de Ressons wrote saillir du coq en l'asne, to leap from the rooster to the donkey, in 1376. A rooster and a donkey have nothing to do with each other, so jumping from one to the other is changing the subject with no link at all. One suggestion is that asne stood for Latin anas, a duck, which would make the pair two birds, but this is not confirmed. In the 1530s Clément Marot gave the name coq-à-l'âne to his rambling satirical verse letters.
