but it is a word that I have never seen

Brannie drops a lot of French inter her posts. I guess we should be grateful she doesn't drop Frisian or Flemish words to confabulate us. The bouquet of the OP made me wonder if English bucket is related. Nope. French bosquet 'thicket' < Germanic bosc 'woods'. And, an anthology is Greek for 'a bunch of flowers', cf. Latin florilegium. Brick on the other hand, is from good old Middle Dutch, bricke, though the OED1 sez it might be from French brique. Dutch has briket from French briquette, (though brik 'brick' is still a dialect word in southern Dutch. English briquets tend to be made out of proto-diamonds, rather than backed stones.

Ceci n'est pas un seing.
