Learn French: Finalement, nous prenons une décision. - Finally, we are making a decision.

In English we "make" a decision, but in French you always "take" a decision (prendre une décision). It is a set phrase, so you must use prendre instead of faire (to make/do).

Is prenons one of the regular -ir verbs we are learning in this lesson?

No! Prenons comes from prendre (to take), which is an irregular verb ending in -re. It is very common, so it often pops up in examples. Notice how it drops the d in the "we" form to become nous prenons.

How do you know décision is feminine (une décision)?

Nouns ending in -sion or -tion in French are almost always feminine. Because of this, we use the feminine article une instead of the masculine un.

Does French have a separate way to say "we are making" versus "we make"?

No, French only has one present tense. Nous prenons translates to both "we make" and "we are making" (or "we take" / "we are taking"). You never need to translate the English "are" when forming the present continuous tense in French.
