[MATANPEER]

what's the meaning of "o" in this sentence?

[Alex276127]

There are ways to form the future tense in Romanian (all of which are grammatically equal)

1. Eu voi, tu vei, el/ea va, noi vom, voi veți, ele/ei vor +the infinitive (without „a„)

2. o+present subjunctive form

3. present tense of a avea (eu am, etc.) + present subjunctive form

This sentence falls into the second category

Are there any rules that apply to know when to use which of these 3 forms?

[crbratu]

Any of the three can be used, it's a matter of style

[Spukyon]

It's part of the verb "o sa fac" which means "I am going to make/I will make". "O sa" basically translates to "will" in this case.
