Origin: 1200–50;Middle Englishamis, equivalent to a-a-1 + mis wrong. See miss1
mid-13c., amis "off the mark," also "out of order," from a "in, on" (see a- (1)) + missen "fail to hit" (see miss (v.)). To take (something) amiss was originally (late 14c.) "to miss the meaning of" (see mistake). Now it means "to misinterpret in a bad sense."
