as far as I can remember

vergessen

mittelhochdeutsch vergeʒʒen, althochdeutsch firgeʒʒan, zu einem Verb mit der Bedeutung »fassen, ergreifen«, eigentlich = aus dem (geistigen) Besitz verlieren

forget 

 

O.E. forgietan, from for-, used here with negative force, "away, amiss, opposite" + gietan "to grasp" (see get). To “un-get,” hence “to lose” from the mind. A common Germanic construction (cf. O.S. fargetan, O.Fris. forjeta, Du. vergeten, O.H.G. firgezzan, Ger. vergessen "to forget"). The literal sense would be "to lose (one's) grip on," but that is not recorded in any Germanic language. Related: Forgetting; forgot; forgotten.
