præterito-præsentia, and given under ágan, 
q. v. The 
inf. dugan and the 
pret. deah, 
pl. dugon, 
retaining preterite inflections, are taken from the 
p. of a strong verb deogan, 
p. deah, 
pl. dugon; 
pp. dogen, ascertained from deah; 
pl. dugon, which shews the ablaut or internal change of the vowel in the 
p. of the twelfth class of Grimm's division of strong verbs [Grm. i. p. 898; Koch, i. p. 252], and requires by analogy with other verbs of the same class the 
inf. deogan and the 
pp. dogen; thus we find the original verb deogan, 
p. deah, 
pl. dugon; 
pp. dogen. The weak 
p. dohte, 
pl. dohton [ = duhte, duhton], is formed regularly from the 
inf. dugan. The same 
præterito-præsens may be generally observed in the following cognate words :--
 | inf. | pres. | pl. | p. | 
| Piers P. Orm. |  | degh, dægh, |  |  | 
| O. Sax | dugan, | dóg, | dugun, |  | 
| O. Frs. | duga, | duch, |  |  | 
| M. H. Ger. | tugen, | touc, |  | tohte, | 
| O. H. Ger. | tugan, | touc, | tugun, 3rd pers. pl. | tohta, | 
| Goth. | dugan, | dáug, | dugum, | daúhta.] |
