Questions & Answers about Upoznat ćemo se na maloj zabavi u njihovom stanu.
Both are grammatically correct; the difference is mainly in word order and emphasis.
Upoznat ćemo se
- This is the most neutral, natural way to say we will meet / we will get to know each other.
- Structure:
- upoznat – short form of the future of upoznati (perfective verb)
- ćemo – auxiliary for we will
- se – reflexive pronoun
Mi ćemo se upoznati
- Also correct, but the mi adds emphasis on we (as opposed to someone else).
- It sounds a bit more contrastive: We will meet (not someone else / at some later point etc.)
- Word order: subject (mi) + auxiliary (ćemo) + clitic se
- infinitive upoznati.
Croatian future tense allows both patterns:
- Upoznat ćemo se sutra.
- Mi ćemo se upoznati sutra.
