Questions & Answers about Misiunea începe mâine.

What does misiunea mean exactly, and why does it end in -a?

Misiunea means the mission.

The basic noun is misiune = mission.
Romanian usually expresses the by attaching the definite article to the end of the noun, instead of putting a separate word in front.

So:

• misiune = mission
• misiunea = the mission

This is a very important Romanian pattern.

What form is începe?

Începe is the 3rd person singular present form of the verb a începe = to begin / to start.

Here it agrees with misiunea, which is a singular noun:

• eu încep = I begin
• tu începi = you begin
• el/ea începe = he/she/it begins

So Misiunea începe literally matches The mission begins.

Why is there no word for it in the sentence?

Romanian often leaves out subject pronouns when they are not needed.

In English, you must say It begins or The mission begins.
In Romanian, the verb ending already helps show the person and number, and here the subject is explicitly present anyway: misiunea.

So Misiunea începe mâine is fully natural without any extra pronoun.

Is începe present tense or future tense here?
