amend (v.)
early 13c., "to free from faults, rectify," from Old French amender "correct, set right, make better, improve" (12c.), from Latin emendare "to correct, free from fault," from ex "out" (see ex-) + menda "fault, blemish," from PIE root *mend- "physical defect, fault" (source also of Sanskrit minda "physical blemish," Old Irish mennar "stain, blemish," Welsh mann "sign, mark").
