4.1.3. (c) Irregular reduplicating verbs
Basing on the data from the Icelandic, it is believed that the Gothic verb bnauan (to rub) belonged to the class of irregular reduplicating verbs. Surviving Gothic sources contain one form of this verb: present participle bnauands (in masc pl, Nom - bnauandans (those rubbing) Luk. VI, 1).
Some degree of atypicality is also displayed by the verbal root hahan (to hang), which is a reduplicating verb in its transitive sense (ushaihah sik (hanged himself)), while in its intransitive sense, builds its preterite forms like class 3 weak verbs do (hahaida - (hung, was suspended)).
It is also, believed, that some of the Gothic weak, suppletive and/or irregular verbs (bauan, trauan, gaggan, and oth) initially belonged to the class of reduplicating strong verbs.
