11.4.3
Jagen ‘to hunt, chase’, vragen ‘to ask’ and waaien ‘to blow (wind)’ are
exceptional mixed verbs in that they all have a strong imperfect and a
weak past participle. Jagen and waaien also have a weak imperfect which
is current, whereas that of vragen is archaic:
jagen joeg/joegen, jaagde/jaagden gejaagd
waaien woei/woeien, waaide/waaiden gewaaid
vragen vroeg/vroegen, vraagde/vraagden gevraagd
But it should be noted that there is a difference in meaning between the
weak and strong imperfects of jagen: joeg/joegen ‘chased away’; jaagde/
jaagden ‘hunted’.
Scheren ‘to shave, shear [a sheep]’ is usually regarded as a strong verb
(see 11.3.1.II) but one commonly hears scheerde as the imperfect of ‘to
shave’.
Ervaren ‘to experience, discover’ should follow varen (see 11.3.1.VI) but
ervaarde is frequently heard in the imperfect by analogy with aanvaarden
‘to accept’, e.g. Hij ervaarde (= ervoer) het als een eer uitgenodigd te worden
‘He regarded it as an honour to be invited’, Hij aanvaardde de eer
uitgenodigd te worden ‘He accepted the honour of being invited’.

Irregular verbs
Colloquially the term ‘irregular’ is used as a synonym for ‘strong’ with
reference to verbs. Strictly speaking, however, irregular verbs are those
that show irregularities that do not follow any of the seven basic patterns
of strong verbs, i.e. classes I to VII.
There are three groups of irregular verbs:
11.5.1
Those that are historically weak verbs that all show a change of vowel in
the past tenses, which they have in common with strong verbs, and also
a dental ending, which they have in common with weak verbs. There are
only six such verbs, two of which are not used in the spoken language,
i.e. dunken and plegen (see 11.3.3). All derivatives of these verbs have the
