(The Merriam-Webster New Book of Word Histories, 1991)
"Aphaeresis has given us a number of new words, like drawing-room
(from withdrawing-room), fend (from defend; whence fender), sport
(from disport), and stain (from distain). A number are aphetic in the
narrow sense: pert (from now obsolete apert, going back ultimately to
Latin appertus 'open'), peal (from appeal), mend (from amend), fray
(from affray), the verb ply (from apply), the adjective live (from
alive), spy (from espy), and tend (from both attend and intend). In
the above cases, significant semantic development followed the
aphaeresis, so that one does not normally connect in one's mind the
shortened and the original longer forms."
