Questions & Answers about De aardbei is ontdooid.
Why does the sentence use is instead of heeft for 'has thawed'?
The verb ontdooien (to thaw) describes a change of state. When it is used intransitively—meaning the subject undergoes the change on its own, without a direct object causing it—it uses zijn as its auxiliary verb in the perfect tense. The strawberry changed from frozen to thawed, so we use is.
How would the auxiliary verb change if I wanted to say 'I have thawed the strawberry'?
Why doesn't the past participle ontdooid start with ge-?
Verbs that start with an inseparable prefix—such as ont-, be-, ver-, her-, or er-—do not get the standard ge- prefix when forming the past participle. Since the verb is ontdooien, the past participle is simply ontdooid.
Why does ontdooid end with a -d instead of a -t?
