duress [duress 词源字典]: duress: [14] Etymologically, duress means literally ‘hardness’, and that was what it was used for when English first acquired it.

endure (v.): late 14c., "to undergo or suffer" (especially without breaking); also "to continue in existence," from Old French endurer (12c.) "make hard, harden; bear, tolerate; keep up, maintain," from Latin indurare "make hard," in Late Latin "harden (the heart) against," from in- (see in- (2)) + durare "to harden," from durus "hard," from PIE *dru-ro-, from root *deru- "be firm, solid, steadfast" (see true).
