Subject Reference in să-Clauses (same vs different subject)

Here is one of the quiet elegances of Romanian. English splits "I want to leave" and "I want you to leave" into two different structures — a bare infinitive for the same subject, an accusative-plus-infinitive ("for you to / you to") for a different one. Romanian uses one construction for both and simply changes the person of the să-verb. Vreau să plec — I want to leave (I leave). Vreau să pleci — I want you to leave (you leave). Nothing else moves; the ending on the conjunctiv verb tells you who acts. Once you grasp that person-marking does all the work, a whole class of sentences that look tricky in English becomes mechanical in Romanian.

The core insight: person, not structure

In English, "want" behaves very differently depending on who does the wanted action:

• Same subject: I want to leave. (infinitive, no second subject)
• Different subject: I want *you to leave.* (you appears as an object, then the infinitive)

These feel like two distinct grammatical patterns. Romanian flattens them into one: vreau + a să-clause, every time. The only thing that distinguishes "I leave" from "you leave" is the conjunctiv verb's ending.

Look at what changed across the three: only the verb ending — plec (I), pleci (you), plecăm (we). The trigger vreau stayed "I want" throughout. In English the structure mutated (infinitive → object + infinitive → "for us to"); in Romanian only one ending shifted.

Same subject: still să, never an infinitive

The most important consequence for an English (or Romance) speaker: even when the subject is the same, Romanian still uses să, not an infinitive. Vreau să plec is "I want to leave" — and there is no shortcut to *vreau a pleca (the bare infinitive, which is archaic or wrong here, as the conjunctiv vs infinitive page details). Romanian refuses to fuse the two verbs the way "want to leave" fuses them in English.

In every one of these the subject never changes, yet să is obligatory. English would use a plain infinitive ("to arrive", "to stay", "to understand"); Romanian conjugates the verb to agree with the same subject. This is the deepest habit to retrain: stop reaching for the infinitive when the subject doesn't change.

Different subject: change the person (and optionally add a pronoun)

When the wanted action is done by someone else, you still use să — you just put the verb in their person. Romanian is "pro-drop", so the new subject often shows up only in the verb ending, with no pronoun at all.

In părinții vor să devină medic, there is no pronoun for "him" at all — the 3sg ending on devină carries the whole "he" meaning. English cannot do this; it must insert "him". This is why Romanian different-subject clauses often look "shorter" than their English equivalents: the subject is baked into the verb.

Naming the different subject explicitly: ca … să

Sometimes you need to spell out the different subject as a full noun or for emphasis — "I want Maria to leave", not just "I want her to leave". When that explicit subject sits inside the subordinate clause, Romanian wraps the clause in ca … să: the ca opens the clause, the new subject follows, and să + verb closes it.

The pattern is: trigger + ca + [explicit subject] + să + verb. The ca is what makes room for a spelled-out subject between the trigger and să. Without an explicit subject to host, you drop ca and use a bare să (vreau să plece prima — "I want her to leave first"). The full mechanics of when ca appears and when it doesn't are on the să vs ca să page; the key point here is that ca is triggered by the need to name a different subject.

A comparison table: English structures, one Romanian construction

Five different English shapes; one Romanian shape that flexes only at the verb ending (plus ca when a noun subject is named). This is the single most economical thing to remember about să-clauses.

Why this is unique even among its relatives

English has the personal-marking infinitive only in clumsy paraphrase ("for us to leave"). Spanish, French, and Italian use a bare infinitive for the same subject (quiero salir) and a subjunctive clause for a different one (quiero que salgas) — so they switch construction depending on the subject, just as English does. Romanian is unusual in using the same finite să-clause for both, letting person-marking alone carry the difference. The Balkan abandonment of the infinitive (shared with Greek, Bulgarian, Albanian) is what made this possible: with no infinitive to fall back on, even the same-subject case had to become a finite clause, and once it did, the two cases collapsed into one.

Why English speakers get this wrong

Two transfer errors dominate. First, learners import the infinitive for the same-subject case — *vreau a pleca for "I want to leave" — because English uses an infinitive there. The fix is absolute: same subject still takes să (vreau să plec).

Second, learners fail to shift the verb's person for a different subject. Under the influence of English "I want you to go" — where "go" stays in its base form — they freeze the Romanian verb in the 1st person: *vreau să plec intending "I want you to leave". But vreau să plec can only mean "I want to leave (myself)". To mean "you", the verb must become pleci. The person of the să-verb is not decoration — it is the subject.

Common Mistakes

Key Takeaways

• Romanian uses one construction — trigger + să
  • verb — for both same-subject and different-subject clauses; English uses two.
• Same subject: still să, never an infinitive (vreau să plec, not *vreau a pleca).
• Different subject: keep să and change the person of the conjunctiv verb (vreau să pleci = I want you to leave); a pronoun is optional because Romanian is pro-drop.
• To name an explicit different subject inside the clause, wrap it in ca … să: vreau ca Maria să plece.
• The verb's person is the subject — don't freeze the verb in the 1st person when someone else is meant.
