MORPHOLOGY: a type of diacritic feature which triggers (or blocks) the
application of a phonological rule. This feature is usually assumed to account
for irregular word formation.
EXAMPLE: Alternations such as foot:feet, goose:geese
and tooth:teeth can be accounted for by assuming that the words foot,
goose and tooth, have a rule feature [+U] which triggers the
phonological umlaut rule.
