Etymology
Clipping of brassiere, borrowed from French brassière, from Old French braciere (originally a lining inside armor to protect the arm, but later a garment), from Old French brace (“arm”), from Latin bracchia, plural of Latin bracchium (“forearm”), from Ancient Greek βραχίων (brakhíōn, “forearm”), from Proto-Hellenic *brəkʰús (“short”) (because the forearm is shorter than the upper arm), inherited from Proto-Indo-European *mréǵʰus.
From bracket, referring to the notation introduced in 1939 by Paul Dirac.
Representing a different pronunciation of bro (“brother”).
