Heinz Giegerich investigates the way in which alternations in the sound
patterns of words interact with the processes of word formation in the
language. Drawing examples from English and German, he uncovers and spells
out in detail the principles of "lexical morphology and phonology," a
theory that has in recent years become increasingly influential in
linguistics. He queries many of the assumptions previously made in it to
produce a formally coherent theory that offers new accounts of some central
phenomena in the phonology of English.
