derivation n
in phonology, the process of applying a set of phonological rules to an
underlying form. For example, in French one can derive a form such as [bõ]
bon(“good”) from an underlying form /bon/ by means of two rules, one of
which nasalizes a vowel before a nasal consonant, the second of which
deletes a syllable-final nasal consonant.
in morphologyand word formation, the formation of new words by
adding affixesto other words or morphemes. For example, the noun
insanityis derived from the adjective saneby the addition of the negative
prefix in- and the noun-forming suffix –ity. Derivation typically results
in changes of parts of speech. It can be contrasted with inflection,
which never changes the lexical category.
in syntax, the process of applying grammatical rules to underlying forms,
for example, in deriving s-structurefrom d-structure.
