A superlative followed by a relative clause — "the best film that I have seen", "the only person who can help" — forces a mood choice in Romanian, and the choice is not mechanical. The rule learners are sometimes given ("use the subjunctive after superlatives") is wrong as stated: Romanian uses the indicative when the relative clause describes a real, identified referent, and the conjunctiv (subjunctive) when it describes one that is merely sought, hypothetical, or possible. This is the same real-vs-sought distinction that governs all relative clauses — superlatives just make it especially visible. Master this and you stop guessing.
The default: indicative for an asserted referent
Most superlative + relative clauses describe something the speaker is claiming to be real and known — a film actually seen, a city actually visited, a meal actually eaten. The relative clause states a fact about that referent, so it stands in the indicative.
E cel mai bun film pe care l-am văzut anul ăsta.
It's the best film (that) I've seen this year. (the film is real and seen → indicative l-am văzut)
Brașov e cel mai frumos oraș pe care l-am vizitat.
Brașov is the most beautiful city I've visited. (real, visited → indicative)
A fost cea mai grea decizie pe care am luat-o vreodată.
It was the hardest decision I've ever made. (a real, taken decision → indicative)
In all of these the event in the relative clause actually happened. The superlative ranks a member of a real, experienced set. English uses the indicative here too, so this case feels natural — the trap is over-extending the "subjunctive after superlatives" rule onto it.
The conjunctiv: a sought or hypothetical referent
The mood flips to conjunctiv (the să-clause) when the relative clause does not describe a known referent but rather specifies what the speaker is looking for, supposing, or imagining — a referent whose existence is open. The verb of the main clause is often one of searching, wanting, needing (a căuta, a vrea, a avea nevoie de, a-și dori), which signals that the thing isn't in hand yet.
Caut cel mai bun preț care să existe pe piață.
I'm looking for the best price there is on the market. (sought, not yet found → conjunctiv care să existe)
Vreau cea mai simplă soluție care să rezolve problema.
I want the simplest solution that will solve the problem. (a solution still to be found → conjunctiv)
Am nevoie de cel mai scurt drum care să mă ducă în centru.
I need the shortest route that gets me downtown. (a route I haven't yet identified → conjunctiv)
The contrast is the same one English draws between "the best price that exists" (asserting it exists) and "the best price there could be" (hypothetical) — but English doesn't change the verb form, so the distinction is invisible in English and must be actively built in Romanian.
Minimal pairs
The cleanest way to feel the rule is to hold the superlative constant and switch only the reality status:
| Indicative (real/known) | Conjunctiv (sought/hypothetical) |
|---|---|
| Vreau cartea cea mai bună pe care o ai. ("the best book you have" — it exists in your stock) | Vreau cea mai bună carte care să existe pe tema asta. ("the best book there is" — whatever it may be, sought) |
| Acela e cel mai mare ajutor pe care mi l-a dat. (a help actually given → indicative) | Caut cel mai mare ajutor pe care să mi-l poată da cineva. (help someone might give → conjunctiv) |
Asta e cea mai bună mâncare pe care am gătit-o.
This is the best food I've cooked. (cooked, real → indicative am gătit-o)
Vreau să gătesc cea mai bună mâncare care să-i placă.
I want to cook the best food that he'll like. (food not yet cooked, goal → conjunctiv care să-i placă)
singurul, unicul, primul, ultimul: the restrictive antecedents
The same logic extends to a family of uniqueness/ordinal antecedents that behave like superlatives because they single out exactly one member of a set: singurul ("the only"), unicul ("the sole"), primul ("the first"), ultimul ("the last"). When these introduce a relative clause about a real, identified referent, the verb is indicative — you are making a factual claim that this is the only/first one.
E singurul coleg care m-a ajutat cu adevărat.
He's the only colleague who really helped me. (a factual claim about a real person → indicative m-a ajutat)
A fost primul care a observat greșeala.
He was the first to notice the mistake. (real, factual → indicative a observat)
Ești ultima persoană pe care aș fi bănuit-o.
You're the last person I'd have suspected. (real referent → indicative, here with the conditional reporting a real suspicion)
But singurul / unicul flip to the conjunctiv when the clause describes a requirement or a sought referent — "the only one that could/would do X" in a hypothetical or future-oriented sense:
Caut singura soluție care să nu coste nimic.
I'm looking for the only solution that wouldn't cost anything. (sought, hypothetical → conjunctiv care să nu coste)
Vreau să fiu singurul care să decidă aici.
I want to be the only one who decides here. (a desired state of affairs → conjunctiv care să decidă)
So even with singurul, the indicative is not automatic: it is the mood of a factual claim (he was, in fact, the only one who helped), while the conjunctiv appears when the uniqueness is projected or required, not asserted.
Why this is one rule, not two
Step back and the superlative case is simply the relative-clause real-vs-sought distinction applied to ranked or unique antecedents. A relative clause takes the indicative when its referent is asserted to exist (caut o carte care e ieftină — "a book that is cheap", presupposing such a book) and the conjunctiv when the referent is merely specified as a target (caut o carte care să fie ieftină — "a book that would be cheap", any such book). Superlatives, singurul, and the ordinals don't add a new rule; they make the same contrast unavoidable because they so often appear with verbs of seeking and wanting.
Vreau un ghid care cunoaște zona.
I want a guide who knows the area. (a specific, existing guide → indicative cunoaște)
Vreau un ghid care să cunoască zona.
I want a guide who knows the area. (any guide meeting the criterion → conjunctiv să cunoască)
That non-superlative pair is the engine; the superlative simply revs it.
Common Mistakes
Applying the conjunctiv mechanically after every superlative:
❌ E cel mai bun film pe care să-l văd.
Wrong — the film was actually seen, so it's a real referent: …pe care l-am văzut.
✅ E cel mai bun film pe care l-am văzut.
It's the best film I've seen.
Using the indicative for a referent that is only being sought:
❌ Caut cel mai ieftin bilet care există.
If you haven't found it, it's hypothetical → conjunctiv: …care să existe (or simply 'cel mai ieftin bilet posibil').
✅ Caut cel mai ieftin bilet care să existe.
I'm looking for the cheapest ticket there is.
Putting singurul + a factual claim in the conjunctiv:
❌ E singurul care să mă fi ajutat.
Wrong — a factual claim about real help takes the indicative: E singurul care m-a ajutat.
✅ E singurul care m-a ajutat.
He's the only one who helped me.
Forgetting that primul/ultimul + a real event is indicative:
❌ A fost primul care să ajungă.
A real arrival → indicative: A fost primul care a ajuns.
✅ A fost primul care a ajuns.
He was the first to arrive.
Mixing the moods within one referent:
❌ Vreau cea mai bună soluție care rezolvă și să fie ieftină.
Inconsistent — a single sought referent stays in one mood: …care să rezolve problema și să fie ieftină.
✅ Vreau cea mai bună soluție care să rezolve problema și să fie ieftină.
I want the best solution that solves the problem and is cheap.
Key Takeaways
- The mood after a superlative depends on the referent's reality status, not on the superlative: indicative for an asserted, known referent (cel mai bun film pe care l-am văzut), conjunctiv for one that is sought or hypothetical (cel mai bun preț care să existe).
- Verbs of seeking/wanting (a căuta, a vrea, a avea nevoie de) pull toward the conjunctiv; verbs reporting a real experience pull toward the indicative — but the true test is always assertion vs. target.
- singurul, unicul, primul, ultimul take the indicative as a factual claim (E singurul care m-a ajutat) and the conjunctiv only when the uniqueness is projected or required.
- This is one rule, not two: it's the relative-clause real-vs-sought distinction (care cunoaște vs. care să cunoască) applied to ranked and unique antecedents.

- Negative Polarity and Concord in DepthC1 — Romanian's negative words (nimic, nimeni, niciodată, nicăieri, niciun, nici) are strict negative-concord items: they demand the clausal nu even when they already mean 'nothing/nobody' (Nu vine nimeni). This page maps the full n-word set, the obligatory-nu rule, their behavior in non-veridical contexts (questions, conditionals, comparatives like mai mult decât oricând), and the positive-vs-negative polarity split (cineva/ceva vs nimeni/nimic) conditioned by veridicality — far subtler than 'double negation'.
