§ 180. A number of verbs with the stem-vowel =ê= in the present (or
final =ai= in the root) hav the ablaut of the =ê--ô=-series (s. §
36). The prt. has the vowel =ô= and reduplication. In the pp. appears
the same vowel as in the prs. These verbs ar divided into two classes
according to the vowel of the prs.:
§ 181. I. Stems ending in a consonant hav =ê= in the prs.; e. g.,
=lêtan=, _to let_, which has =lêta=, =laílôt=, =laílôtum=, =lêtans=. Of
this kind ar also =grêtan= (=gaígrôt=), _to weep_; =têkan= (=taítôk=),
_to tuch_; =-rêdan= (=raírôþ=), _to counsel_.
§ 182. II. Roots ending in a vowel change the =ê= into =ai= (§ 22).
Here belong: =saian=, _to sow_: =saia=, =saísô=, =saísôum=, =saians=
(concerning other forms, cp. § 22, n. 1; § 170, n. 2), and =waian=
(=waíwô=), _to blow_.
NOTE. The prt. of =faian=, _to blame_, is not extant; cp. § 22, n.
