Learn Dutch: Ik zal mijn sleutel niet verliezen.

When you use a helping verb like zal to make the future tense, the main action verb (verliezen) always gets pushed to the very end of the sentence in its full dictionary form (the infinitive).

Is zal a regular verb form for ik?

Zullen (will/shall) is an irregular verb. For ik, the form is zal. For hij, zij, and het (he, she, it), the form is also zal without the usual extra -t at the end. For jij (you), you can use either zal or zult.

Why does niet go after mijn sleutel instead of right after zal?

In Dutch, niet generally comes after the specific object of the sentence, which here is mijn sleutel (my key). Because verliezen is pushed to the end by the future tense rule, niet ends up sitting right between the object and the final verb.

Could I use ga instead of zal to talk about the future here?
