The moment you start having real opinions in Polish — this café is better than that one, this phone is cheaper but worse — you need comparison. The grammar behind it is not hard, but it forces three decisions English speakers never have to make: niż or od?, taki sam or ten sam?, and remembering that "good" and "bad" have irregular comparatives. This page is a phrase bank for comparison in talk — the structures you actually reach for in conversation, drilled through exchanges.
"Better/worse than": the two ways to say "than"
A comparative adjective (like lepszy "better") needs a way to attach the thing you are comparing against. Polish gives you two, and choosing between them is the central skill of this page. (For the full treatment, see niż vs od.)
Option 1 — niż + same case. Niż is a conjunction; the noun after it stays in whatever case it would have on its own. In the simplest sentences that means the nominative.
Ten film jest lepszy niż tamten.
This film is better than that one.
Option 2 — od + genitive. Od is a preposition, so the thing you compare against goes into the genitive case. Tamten → tamtego.
Ten film jest lepszy od tamtego.
This film is better than that one.
Both sentences mean the same thing. Od + genitive is shorter and very common in speech for simple two-item comparisons; niż is preferred (and often required) when the comparison is more complex — comparing two verbs, two clauses, or when the second element is itself in an oblique case.
Wolę kawę niż herbatę.
I prefer coffee to tea (lit. coffee rather than tea).
Pracuję teraz mniej niż dawniej.
I work less now than I used to.
The irregular comparatives: dobry/zły and friends
Just like English "good → better" (not "gooder"), Polish has a handful of irregular comparatives you simply must know, because they are the most frequent ones in conversation. (See the comparative page for the regular -szy pattern.)
| Adjective | Comparative | Superlative |
|---|---|---|
| dobry (good) | lepszy | najlepszy |
| zły (bad) | gorszy | najgorszy |
| duży (big) | większy | największy |
| mały (small) | mniejszy | najmniejszy |
| wysoki (tall/high) | wyższy | najwyższy |
| lekki (light) | lżejszy | najlżejszy |
Mój nowy telefon jest tańszy, ale gorszy od poprzedniego.
My new phone is cheaper, but worse than the previous one.
To było najlepsze wesele, na jakim byłam.
That was the best wedding I've ever been to.
"More / less … than": bardziej and mniej
Not every adjective forms a one-word comparative. Longer adjectives, participles, and many borrowed words use the analytic pattern bardziej ("more") / mniej ("less") + the plain adjective — exactly like English "more interesting." (The full -szy vs bardziej split lives on the comparative page.)
Ta książka jest bardziej interesująca niż film.
This book is more interesting than the film.
Jestem teraz mniej zmęczony niż wczoraj.
I'm less tired now than yesterday.
A frequent learner error is doubling up: bardziej lepszy is wrong, the way "more better" is wrong in English. Use bardziej only with adjectives that have no one-word comparative.
"The same": ten sam vs taki sam
Here is a distinction English collapses into one word — "same" — but Polish splits in two, and getting it wrong changes your meaning. (See sam and taki.)
- ten sam = the very same one — numerically identical, one single thing.
- taki sam = the same kind — a separate thing that is just like it.
Mamy ten sam samochód — kupiliśmy go razem.
We have the same (one) car — we bought it together.
Mamy taki sam samochód — ja kupiłem swój w zeszłym roku.
We have the same (kind of) car — I bought mine last year.
"Different from": inny niż / inny od
The opposite of "the same" is inny ("different, other"). It attaches "from" with either niż or od + genitive, just like comparatives.
Twój pomysł jest zupełnie inny niż mój.
Your idea is completely different from mine.
Życie na wsi jest inne od życia w mieście.
Life in the countryside is different from life in the city.
"As … as" and "the more … the more"
For equality, Polish uses tak… jak ("as… as"):
Jest tak wysoki jak jego brat.
He's as tall as his brother.
Nie jest tak drogo, jak myślałem.
It's not as expensive as I thought.
And for proportional comparison ("the more… the more"), the elegant im… tym construction — note that im takes the comparative, and so does tym:
Im więcej się uczę, tym mniej rozumiem.
The more I study, the less I understand.
"I prefer X to Y": wolę X od Y / niż Y
To state a preference in conversation, the go-to verb is woleć ("to prefer"). It pairs naturally with both od + genitive and niż.
Wolę górę od morza.
I prefer the mountains to the sea.
Zdecydowanie wolę gotować w domu, niż jeść na mieście.
I definitely prefer cooking at home to eating out.
Notice the second example uses niż because what follows is a verb phrase (jeść na mieście), not a single noun — exactly the situation where od is impossible.
A comparison exchange
— Który laptop jest lepszy? — Ten jest droższy, ale dużo szybszy od tamtego.
— Which laptop is better? — This one is more expensive, but a lot faster than that one.
— Macie takie same kurtki! — Nie, mamy tę samą — pożyczam ją od siostry.
— You've got the same jackets! — No, we've got the same one — I borrow it from my sister.
Common Mistakes
❌ Ten jest lepszy od tamten.
Incorrect — od requires the genitive: tamten → tamtego.
✅ Ten jest lepszy od tamtego.
This one is better than that one.
❌ Wolę kawę od pić herbatę.
Incorrect — od can't take a verb phrase; use niż before a verb.
✅ Wolę pić kawę niż herbatę.
I prefer drinking coffee to tea.
❌ To jest bardziej dobre niż tamto.
Incorrect — dobry has an irregular one-word comparative; don't use bardziej with it.
✅ To jest lepsze niż tamto.
This is better than that.
❌ Mamy taki sam samochód — kupiliśmy go razem.
Incorrect — if it's literally one shared car, use ten sam, not taki sam.
✅ Mamy ten sam samochód — kupiliśmy go razem.
We have the same (one) car — we bought it together.
❌ Jest tak wysoki jak i jego brat.
Incorrect — the equality frame is simply tak… jak; the extra i doesn't belong here.
✅ Jest tak wysoki jak jego brat.
He's as tall as his brother.
Key Takeaways
- "Than" is niż (same case) or od + genitive — od is the snappy spoken choice for simple nouns; switch to niż before pronouns in other cases, clauses, or verbs.
- Memorize the irregular comparatives lepszy / gorszy / większy / mniejszy — they are the most frequent ones in speech.
- Use bardziej / mniej only with adjectives that lack a one-word comparative; never bardziej lepszy.
- ten sam = the very same object; taki sam = the same kind of thing.
- Inny and woleć both attach "than/to" with niż or od
- genitive, following the same logic as comparatives.
