[Cunnan is the second of the twelve Anglo-Saxon verbs, called præterito-præsentia, given under ágan, q. v. The inf. cunnan and the pres. can, pl. cunnon, retaining preterite inflections, are taken from the p. of the strong verb cinnan, ascertained from can, pl. cunnon, which shews the ablaut or internal change of the vowel in the p. tense of the twelfth class of Grimm's division of strong verbs [Grm. i. edn. 2, p. 898; Koch, i. p. 252], and requires, by analogy with other verbs of the same class, the inf. cinnan, q. v. and the pp. cunnen. Thus we find the original verb cinnan, p. can, pl. cunnon; pp. cunnen. The weak p. cúðe, pl. cúðon, for cunde, cundon, is formed regularly from the inf. cunnan. The pp. generally takes the weak form, in Anglo-Saxon as well as in the cognate words; but strong and weak forms are both found, in A. Sax. the strong on-cunnen, and the weak cúþ, and in M. H. Ger. the strong ver-kunnen, and the weak kunt. The same præterito-præsens may be generally observed in the following cognate words :--
