To review: a strong verb forms a past tense through vowel changes. For example, drincan ‘to drink’ becomes dranc (1st person singular preterite), druncon (plural preterite), and (ge)druncen (past participle).

A weak verb forms a past tense by adding d (or sometimes t). For example, fremman ‘to perform, do’ becomes fremede, fremedon, and gefremed.

With these things in mind, see below.

1. agan to own, possess, have power over

Present		Past
ic ah	we agon	ic ahte	we ahton
þu ahst	ge agon	þu ahtest	ge ahton

2. cunnan can, to know how to

Present		Past
ic cann	we cunnon	ic cuþe	we cuþon
þu canst	ge cunnon	þu cuþest	ge cuþon

3. dugan to avail, be of use, be good
