ABSTRACT

Regular synchronic sound alternation in etymologically related words. (a) In automatic (or ‘complementary’) alternation the sound change is conditioned through the phonetic context, cf. the alternation of [aι] ~ [ι] in divine ~ divinity, crime ~ criminal, conditioned through change in syllable stress. (b) Morphophonemic alternation differentiates words grammatically, such as through ablaut in tense formation (sing-sang-sung) and word formation (bind-band-bound), and umlaut in plural formation (woman-women). ( also allomorph, morphophoneme)
