For the formation of the [past participle](#/lesson/Verbs.Re12), we conjugate the verb separately from its prefix. Then, we attach the prefix to the beginning of the past participle.
_Afwerken_ (to finish, to give the finishing touch)
- The verb consists of the prefix _af_ and the verb _werken._
- Recall, that we get the past participle as follows:
ge+stam+t = ge+werk+t = gewerkt
- Then, we attach the prefix _af_ to the beginning, so that the past participle becomes:
prefix + past participle = af+gewerkt = _afgewerkt_
Another example:
_Goedkeuren_ (to approve)
- ge+stam+d = ge+keur+d = gekeurd
- goed+gekeurd = _goedgekeurd_
