I mentioned, recentlyish, being both good and brave.
I have been wondering, on and off, over the about -- well, "brav" is the German for "good" (in the sense of well-behaved), so... cognate???
I was initially plerplexed by poking at etymonline and wiktionary, both of which specify
From Middle French brave, borrowed from Italian bravo, itself of uncertain origin...
... but NOPE that's also where we get brav from!
Bonus: etymonline also encouraged me to look up Old English "modig" ("(now "moody")"), in some startlement, because that sure does look like "mutig" i.e. the German for "brave"! ... yep, they're cognate too. I am charmed by the semantic drift!
