🎯

The 'O FI' Shortcut

In 90% of spoken situations, you can just use 'o fi' for all persons (I, you, he, we, etc.). It makes you sound very natural and saves you from conjugating!

🎯

The 'O' Shortcut

In speech, always use 'o' instead of 'va' for the presumptive. 'Va fi lucrând' sounds like a textbook; 'O fi lucrând' sounds like a native.

🎯

The 'Trebuie' Hack

If you're unsure, always use 'trebuie'. It never changes for person, so it's your safest bet for expressing any kind of 'must' or 'should'.

Common Questions (6)

Yes, you can say Probabil că doarme. However, using O fi dormind sounds more native and spontaneous in conversation.
In informal speech, yes. You can say Eu o fi lucrând, Tu o fi lucrând, etc. In formal writing, you should conjugate the auxiliary (oi fi, îi fi, or fi).
Only if you are using it as a noun or in very specific archaic constructions. Always use 'să' for verbs.
No, it can be the verb 'a putea'. Check if it conjugates.
Yes, but it's redundant. 'Poate o fi plecat' is common in speech but 'O fi plecat' already implies 'poate'.
It's neutral-informal. In very formal writing, you'd use 'este posibil să' or the full auxiliary 'va fi'.
