Once you can form an adverb (szybko "quickly", dobrze "well"), you can compare it: "faster", "better", "the fastest", "the best". Polish adverb comparison runs exactly parallel to adjective comparison — a synthetic comparative in -ej, a superlative made by prefixing naj-, and an analytic alternative with bardziej / najbardziej. The catch is that the four most useful comparative adverbs in the whole language — lepiej, gorzej, więcej, mniej — are suppletive: their forms have nothing to do with the positives dobrze, źle, dużo, mało. You memorise them, and you use them every single day.
The regular comparative: -ej
To form the comparative, take the adverb and replace its ending with -ej, usually with a consonant change (softening) in the stem:
| Adverb | Comparative | Meaning |
|---|---|---|
| szybko | szybciej | faster |
| wolno | wolniej | slower |
| ładnie | ładniej | more nicely |
| tanio | taniej | more cheaply |
| ciepło | cieplej | more warmly |
| późno | później | later |
Możesz mówić wolniej? Nie nadążam.
Can you speak slower? I can't keep up.
Przyjdź jutro trochę później, koło dziewiątej.
Come a bit later tomorrow, around nine.
Tutaj kupisz to taniej niż w centrum.
You'll buy it cheaper here than in the centre.
The superlative: naj- + comparative
The superlative is dead simple: stick naj- on the front of the comparative. Szybciej → najszybciej, później → najpóźniej, taniej → najtaniej.
Kto z was biega najszybciej?
Which of you runs the fastest?
Najlepiej zadzwoń do niej wieczorem.
It's best to call her in the evening.
To miejsce, gdzie najtaniej zjesz w mieście.
This is the place where you'll eat most cheaply in the city.
The analytic comparative: bardziej / najbardziej
Some adverbs — especially longer ones, participle-based ones, and those describing a quality of degree rather than manner — form the comparative with bardziej ("more") and the superlative with najbardziej ("most"), placed before the unchanged adverb. This mirrors English "more carefully / most carefully".
Musisz tłumaczyć to bardziej szczegółowo.
You need to explain it more thoroughly.
To jego najbardziej znany utwór.
That's his most famous piece.
Słuchaj go bardziej uważnie.
Listen to him more attentively.
There is no perfectly sharp rule for when to use -ej versus bardziej; high-frequency, short adverbs of manner take -ej (szybciej, wolniej, ładniej), while bardziej is the safe default for anything that resists the synthetic form. When in doubt, bardziej + adverb is rarely outright wrong, though it can sound clumsy where a one-word -ej form exists.
The suppletive irregulars — learn these cold
These four are the heart of the page. They are the most frequent comparison words in Polish, and they are suppletive — completely unrelated to their positive forms:
| Positive | Comparative | Superlative | Meaning |
|---|---|---|---|
| dobrze (well) | lepiej | najlepiej | better / best |
| źle (badly) | gorzej | najgorzej | worse / worst |
| dużo (much) | więcej | najwięcej | more / most |
| mało (little) | mniej | najmniej | less / least |
Notice the diacritics: lepiej, gorzej, więcej (with ę), mniej. There is no logic connecting dobrze to lepiej or dużo to więcej — just as English "good → better" is unrelated, so are these. There is no shortcut; drill them until they are automatic.
Dzisiaj czuję się lepiej niż wczoraj.
Today I feel better than yesterday.
Im więcej o tym myślę, tym gorzej się czuję.
The more I think about it, the worse I feel.
Najlepiej gotuje mama.
Mum cooks best (of all).
Powinieneś mniej pracować, a więcej odpoczywać.
You should work less and rest more.
więcej and mniej govern the genitive
Here is the trap that distinguishes the irregular quantity adverbs from the rest. więcej and mniej behave like quantifiers: when a noun follows, it goes into the genitive, just like dużo and mało. So it is więcej czasu ("more time", genitive czasu), mniej pieniędzy ("less money", genitive plural pieniędzy) — never the nominative.
Potrzebuję więcej czasu.
I need more time.
Mam teraz mniej pieniędzy niż kiedyś.
I have less money now than I used to.
Zjadłeś więcej zupy niż ja.
You ate more soup than I did.
This genitive government is shared with the quantity words on the dużo / kilka / parę page — więcej and mniej are simply their comparative forms and inherit the same case behaviour. As pure manner adverbs (modifying a verb, no noun following), they take no case: pracuj mniej ("work less").
The standard of comparison: niż or od
To say "X-er than Y", Polish offers two constructions, exactly as with adjectives:
- niż
- the same case as the first element (usually nominative): szybciej niż ty ("faster than you").
- od
- genitive: szybciej ode mnie ("faster than me").
Biegam szybciej niż ty.
I run faster than you.
Biegam szybciej od ciebie.
I run faster than you. (od + genitive)
Ona zarabia więcej niż jej szef.
She earns more than her boss.
The two are interchangeable in most contexts; the choice and its finer points are covered on the niż vs od page, which applies equally to adverbs. One memory hook: od always pulls the genitive (ode mnie, od ciebie, od niego), while niż simply repeats whatever case the compared item already had.
Common Mistakes
❌ Czuję się bardziej dobrze.
Incorrect — dobrze has the suppletive comparative lepiej; you cannot use bardziej with it
✅ Czuję się lepiej.
I feel better.
❌ Potrzebuję więcej czas.
Incorrect — więcej governs the genitive; 'time' must be czasu
✅ Potrzebuję więcej czasu.
I need more time.
❌ Najbardziej szybko biega Marek.
Incorrect — szybko has the synthetic superlative najszybciej; the analytic form is wrong here
✅ Najszybciej biega Marek.
Marek runs the fastest.
❌ Mam mniej pieniądze niż ty.
Incorrect — mniej takes the genitive plural pieniędzy
✅ Mam mniej pieniędzy niż ty.
I have less money than you.
❌ Dzisiaj jest gorzej niż wczoraj... napisane jako 'gożej'.
Incorrect spelling — 'worse' is gorzej, with rz, not ż
✅ Dzisiaj jest gorzej niż wczoraj.
Today is worse than yesterday.
Key Takeaways
- Comparative = -ej (szybciej, wolniej, później) or analytic bardziej; superlative = naj-
- comparative (najszybciej, najbardziej...).
- The four suppletive irregulars lepiej, gorzej, więcej, mniej are the highest-frequency comparison words and must be memorised — they don't derive from dobrze/źle/dużo/mało.
- więcej and mniej govern the genitive when a noun follows (więcej czasu, mniej pieniędzy), behaving like quantifiers.
- "Than" = niż (same case) or od
- genitive — see niż vs od.
