" In linguistic change caused by folk etymology, the form of a word changes so that it better matches its popular rationalisation. For example:-
Old English sam-blind ("semi-blind" or "half-blind") became sand-blind (as if "blinded by the sand") when people were no longer able to make sense of the element sam ("half")."
