Grammar.
- : regular alternation in the internal phonological structure of a word element, especially alternation of a vowel, that is coordinated with a change in grammatical function or combination, as in English sing, sang, sung, song; apophony.

The vowels vary within certain series of related vowels, called ablaut-series.
The strong verbs form their preterite (originally the perfect) and past participle by means of ablaut ( 12).
The non-reduplicated verbs are divided into six classes according to the six ablaut-series ( 12).
The verbs of this class belong to the sixth ablaut-series ( 12), and accordingly have a in the present; uo in the pret.
The verbs of this class belong to the fourth ablaut-series ( 12).
