Learn Dutch: Wij verdelen onze taken voor het project. - We divide our tasks for the project.

No, verdelen is an inseparable verb. A helpful rule to remember: verbs starting with the prefixes ver-, be-, ge-, or ont- are never separable. If this were a subordinate clause, it would not split apart but simply move to the end: ... dat wij onze taken voor het project verdelen.

Why do we use onze here instead of ons?

Taken (tasks) is plural, and all plural nouns in Dutch behave like de-words. For de-words, the word for "our" is always onze. You only use ons for singular het-words (so if you were talking about "our project", it would be ons project).

Where did the second 'a' go when making the plural taken?

The singular word is taak (task). When we add -en to make it plural, the word divides into syllables like this: ta-ken. Because that first syllable now ends in a vowel, the "a" is naturally pronounced long, so Dutch spelling rules say we must drop the extra "a".

If I wanted to put "for the project" at the start of the sentence, how would the word order change?
