Etymology
Origin of apropos
First recorded in 1660–70; from French à propos literally, “to purpose,” from Latin ad prōpositum; see ad-, proposition
Explanation
Apropos means regarding or appropriate to, as in: Apropos of your interest in fishing, your grandfather gave you his set of championship lures, rods, reels and lucky tackle box. Apropos is a useful word to learn. But first you have to know how to pronounce it: AP-rə-pō. Then you can conveniently change the subject of a conversation by using the expression "Apropos of nothing," which is a glib way of saying, "Oh, and by the way..." If someone's remarks are suitable and appropriate to the occasion, you can get on their good side by saying: How apropos!
