"He begins immediately."

[pvnrt]

"Hij start onmiddelijk" "Hij begint onmiddellijk", the spelling changes when the verb changes?

[xMerrie]

No, I guess that's a typo. It's always 'onmiddellijk'.

[pvnrt]

Thank you.

Why does the adverb have to be at the end of the sentence?

[El2theK]

Opposed to?

Typical word order = Subject (Hij), Verb (begint), Rest (onmiddelijk)
