Comparing adverbs in Romanian works almost exactly like comparing adjectives: the language is fully analytic. There are no comparative suffixes — no equivalent of English "-er" or "faster," "sooner," "harder." You put mai in front for "more," mai puțin for "less," and cel mai for "the most." If you have already learned adjective comparison, you have learned 90% of this page for free.
The remaining 10% is the part that trips everyone up: the suppletive adverbs. A handful of the commonest adverbs — bine, rău, mult, puțin — form their comparatives from what looks like a different root, and crucially they keep the adverb form, not the adjective one. "Better" as an adverb is mai bine, never mai bun (that's the adjective). Romanian's rare suppletion lives almost entirely in this little cluster, so it's worth isolating and memorizing.
Superiority: mai … decât (more … than)
Put mai before the adverb and decât before the standard of comparison. Both mai and decât are invariable, and the adverb itself never changes form (adverbs don't agree with anything).
Alergi mai repede decât mine, nu te pot ajunge.
You run faster than me, I can't catch up.
Vorbește mai rar, te rog, ca să înțeleg.
Speak more slowly, please, so I can understand.
A ajuns mai devreme decât ne așteptam.
He arrived earlier than we expected.
Note the contrast with English in the first two: English has the synthetic faster but the analytic more slowly. Romanian does not care how long the adverb is — repede ("fast") and rar ("slowly") both just take mai. After decât, a pronoun appears in its strong (stressed) form: decât mine, decât tine, decât el.
Inferiority: mai puțin … decât (less … than)
For "less," replace mai with mai puțin. The than-word stays decât — you are still comparing two unequal things.
Anul ăsta călătoresc mai puțin des decât anul trecut.
This year I travel less often than last year.
Lucrează mai puțin eficient când e obosit.
He works less efficiently when he's tired.
Equality: la fel de … ca (as … as)
For "as … as," Romanian wraps la fel de around the adverb and uses ca (not decât) before the second term. Remember the split learned with adjectives: decât for inequality, ca for equality.
Cântă la fel de bine ca sora ei.
She sings as well as her sister.
Mașina nouă consumă la fel de mult ca cea veche.
The new car uses as much fuel as the old one.
Nu scriu la fel de frumos ca tine.
I don't write as nicely as you.
You may also hear tot atât de … ca and deopotrivă de with the same equality meaning (the latter is more literary).
The relative superlative: cel mai (the most)
To express "the most," Romanian uses cel mai before the adverb (and cel mai puțin for "the least"). Here is a point worth flagging: with adjectives, the cel part agrees in gender and number (cel mai bun / cea mai bună / cei mai buni). With adverbs there is nothing to agree with — adverbs have no gender or number — so the form is invariably cel mai, no matter who is doing the action.
Dintre toți, ea conduce cel mai prudent.
Of everyone, she drives the most carefully.
Maria și Ana au terminat cel mai repede.
Maria and Ana finished the fastest.
In that second example, the subject is feminine and plural, yet the superlative adverb stays cel mai repede — not cele mai repede. Compare the adjective, which would agree: Sunt cele mai rapide ("they are the fastest [ones]"). This is the single clearest way to tell whether you are looking at an adverb or an adjective: if cel refuses to agree, it's modifying a verb, so it's an adverb.
The suppletive adverbs: bine, rău, mult, puțin
Most adverbs compare with a plain mai. But four extremely frequent adverbs have suppletive comparatives — the comparative root differs from the base — and this is exactly where the adverb form must be kept distinct from the adjective.
| Adverb (base) | Comparative | Superlative | English |
|---|---|---|---|
| bine (well) | mai bine | cel mai bine | well → better → best |
| rău (badly) | mai rău | cel mai rău | badly → worse → worst |
| mult (much) | mai mult | cel mai mult | much → more → most |
| puțin (little) | mai puțin | cel mai puțin | little → less → least |
The trap is bine. The adverb "well/better/best" is bine → mai bine → cel mai bine. The adjective "good/better/best" is the completely different word bun → mai bun → cel mai bun. English keeps them apart too (the adverb "well" vs. the adjective "good"), but English speakers routinely substitute "good" for "well" in casual speech ("I did good"), and they carry that habit into Romanian — producing the wrong word entirely, not just the wrong ending.
Gătește mai bine decât oricine din familie.
He cooks better than anyone in the family.
Mă simt mai rău azi decât ieri.
I feel worse today than yesterday.
Îmi place cel mai mult înghețata de ciocolată.
I like chocolate ice cream the most.
Dintre toți colegii, el muncește cel mai mult.
Of all the colleagues, he works the most.
Notice that mai mult and mai puțin serve double duty: they are the suppletive comparatives of the adverbs mult/puțin ("more/less" as in "I read more"), and they are also the very particles used to build inferiority comparatives of other adverbs (mai puțin des). Romanian recycles the same two words for both jobs.
Common Mistakes
Importing an English adverb suffix onto a Romanian adverb:
❌ Aleargă repedeer decât mine.
Nonsense form — Romanian has no -er. Use mai repede.
✅ Aleargă mai repede decât mine.
He runs faster than me.
Using the adjective bun where the adverb bine is needed:
❌ Cântă mai bun decât mine.
Incorrect — to modify a verb you need the adverb: mai bine.
✅ Cântă mai bine decât mine.
She sings better than me.
Agreeing cel with the subject when it modifies a verb (treating an adverb like an adjective):
❌ Fetele au terminat cele mai repede.
Incorrect — adverbial superlative is invariable: cel mai repede.
✅ Fetele au terminat cel mai repede.
The girls finished the fastest.
Using ca for inequality or decât for equality (mixing the than-words):
❌ Vorbește mai rar ca mine.
Incorrect — inequality takes decât, not ca.
✅ Vorbește mai rar decât mine.
He speaks more slowly than me.
Dropping de from la fel de:
❌ Cântă la fel bine ca tine.
Incorrect — the equality frame is la fel de … ca.
✅ Cântă la fel de bine ca tine.
She sings as well as you.
Key Takeaways
- Adverb comparison is fully analytic: mai (more), mai puțin (less), la fel de … ca (as … as), cel mai (the most). No suffixes.
- decât = than (unequal); ca = as (equal). Same split as adjectives.
- The superlative cel mai is invariable for adverbs — it never agrees, because adverbs have no gender or number. Agreement (cea mai, cei mai, cele mai) signals an adjective.
- The suppletive set lives in the adverbs: bine→mai bine (not mai bun), rău→mai rău, mult→mai mult, puțin→mai puțin. Keep the adverb bine apart from the adjective bun.
