Questions & Answers about Dan zal het inkomen in één decennium zijn verdubbeld.
How is the future perfect tense built in this sentence?
It uses zal (will) combined with zijn verdubbeld (have doubled). To form the future perfect in Dutch, you use a conjugated form of zullen in the second position, and send the infinitive of the helping verb (zijn or hebben) plus the past participle to the end of the sentence.
Why does this sentence use zijn instead of hebben for the perfect tense?
Can I swap the order of the verbs at the end to verdubbeld zijn?
Yes, you absolutely can! In a Dutch verb cluster at the end of a sentence, the auxiliary verb (zijn) and the past participle (verdubbeld) can go in either order. Both zijn verdubbeld and verdubbeld zijn are grammatically correct and mean the exact same thing.
Why does the verb zal come before the subject het inkomen?
Because the sentence starts with the adverb Dan (Then). Whenever you start a main clause with a time word or any element other than the subject, it triggers inversion. The verb must stay in the second position, so zal jumps in front of the subject het inkomen.
Why are there accent marks on the word één?
The accents show that it represents the number one rather than the article a or an, which is written as een without accents. It emphasizes that the income will double in exactly one decade, not just a decade.
