Questions & Answers about Heb je het werk al gedaan?
Where does the word gedaan come from?
It is the irregular past participle of the verb doen (to do). Just like in English (do -> done), it is irregular and needs to be memorized. Here, it pairs with the helping verb heb to mean "have done".
Why is gedaan at the very end of the sentence?
This is a classic Dutch sentence structure! When you use a past tense with a helping verb, the helping verb (heb) stays near the beginning, but the past participle (gedaan) gets pushed all the way to the end of the sentence.
Can I put al at the end, like in the English "Have you done the work already?"
No, because the past participle (gedaan) insists on being at the very end of the sentence. Adverbs like al (already) are placed before that final verb.
Why is it Heb je instead of Hebt je? Doesn't the je form get a -t at the end?
Normally, yes (you would say je hebt). But to ask a yes/no question, you swap the verb and subject. When je or jij comes right after the verb, the verb drops its -t ending. So, it becomes Heb je.
