4.2.1. (b) I class weak irregular verbs
Some weak verbs of this class (e.g. brukjan (to use, employ), bugjan (to buy), þagkjan (to think), þugkjan (to think, consider; to seem); waúrkjan (to make, do; to work) and oth), whose stems ended in velar consonants k, ŋ, g, formed their past tense by means of the suffix -ta (while the verbal stem lost the marker of this class -j-); the combination of this velar consonat and the consonant -t of the suffix resulted in -ht-: bugjan → bauhta, brūkjan → brūhta, waúrkjan → waúrhta. In addition, in verbs þagkjan, þugkjan [-ŋkjan], the nasal consonant -ŋ- was dropped and the stem vowel became lengthened, which resulted in the following past tense forms of these two verbs: þāhta and þūhta. The past tense of the verb borrowed from Greek kaupatjan (to buffet, slap) is kaupasta [<*kaupat + -ta].
Past tense/preterite forms of the preterite-present verbs have the same structure.
| I class irregular |
infinitive | preterite singular | preterite plural | past participle |
| to think | þagkjan | þāhta | þāhtēdum | þāhts |
| to make, do; to work | waurkjan | waurhta | waurhtēdum | waurhts |
