Czech adjectives fall into two great classes. The big, busy one is the hard type (mladý), with its long vowels -ého, -ému, -ým. This page covers the other one — the soft type — and the good news is that it is by far the easier of the two. Its model word is jarní (spring-, vernal), and its defining trick is that a single ending, -í, does the work of three genders at once. Where the hard adjective spreads itself across -ý / -á / -é, the soft adjective just sits there: jarní den (a spring day, masculine), jarní noc (a spring night, feminine), jarní ráno (a spring morning, neuter) — one form, three genders, no change.
One ending for all three genders
In the nominative singular the contrast with the hard type is stark. Watch what a hard adjective does to the same three nouns, and what the soft one refuses to do:
| Masculine (den) | Feminine (noc) | Neuter (ráno) | |
|---|---|---|---|
| Hard (teplý) | teplý den | teplá noc | teplé ráno |
| Soft (jarní) | jarní den | jarní noc | jarní ráno |
The hard adjective has three different endings; the soft adjective has one. That single -í is the whole personality of the class.
Konečně je tady první teplý jarní den.
The first warm spring day is finally here. (masculine — both adjectives modify den, but only the hard one shows -ý)
Byla to krátká, ale krásná jarní noc.
It was a short but beautiful spring night. (feminine — jarní unchanged next to the hard krásná)
Mám rád tiché jarní ráno, když ještě nikdo nespí.
I love a quiet spring morning when no one is awake yet. (neuter — jarní again unchanged)
The full paradigm of jarní
| Singular | Masc. animate | Masc. inanimate | Feminine | Neuter |
|---|---|---|---|---|
| Nom. | jarní | jarní | jarní | jarní |
| Gen. | jarního | jarního | jarní | jarního |
| Dat. | jarnímu | jarnímu | jarní | jarnímu |
| Acc. | jarního | jarní | jarní | jarní |
| Loc. (o…) | jarním | jarním | jarní | jarním |
| Instr. | jarním | jarním | jarní | jarním |
| Plural | Masc. animate | Masc. inanimate | Feminine | Neuter |
|---|---|---|---|---|
| Nom. | jarní | jarní | jarní | jarní |
| Gen. | jarních | jarních | jarních | jarních |
| Dat. | jarním | jarním | jarním | jarním |
| Acc. | jarní | jarní | jarní | jarní |
| Loc. (o…) | jarních | jarních | jarních | jarních |
| Instr. | jarními | jarními | jarními | jarními |
Count the distinct shapes in those two tables and you will find only six of them: jarní, jarního, jarnímu, jarním, jarních, jarními. The hard type, by comparison, has roughly twice as many. Two facts make the soft type so economical. First, the entire feminine column is just jarní — it never moves at all, in any case, singular or plural. Second, the masculine and neuter share their forms almost everywhere. So in practice you only ever have to choose between the masculine/neuter set (jarního, jarnímu, jarním) and the invariable feminine jarní.
Where soft adjectives come from
The soft class is not a random list — it has a clear semantic signature. Soft adjectives are overwhelmingly derived from nouns and adverbs of time and place, plus a layer of relational and "main/other" meanings. Once you notice the pattern, you can often predict the class before you even see the ending:
- Time: letní (summer, from léto), zimní (winter, from zima), podzimní (autumn), ranní (morning, from ráno), večerní (evening), dnešní (today's, from dnes), včerejší (yesterday's), poslední (last), příští (next), nynější (present-day).
- Place: zdejší (local, from zde), sousední (neighbouring), vedlejší (adjacent, side-), přední (front), zadní (back), horní (upper), dolní (lower).
- Relational / other: cizí (foreign, strange), hlavní (main), domácí (home, domestic), vlastní (one's own), společný… no — that one is hard; but obecní (communal), školní (school-), lidský… also hard. The reliable cue is the -í ending itself, not the meaning alone.
Mám nejradši dlouhé letní večery u vody.
I like long summer evenings by the water best. (letní = soft, from léto)
Promiň, to je nějaké cizí slovo, vůbec ho neznám.
Sorry, that's some foreign word, I don't know it at all. (neuter — cizí slovo)
Hlavní nádraží najdeš na konci téhle ulice.
You'll find the main station at the end of this street.
O dnešním zápase se bude ještě dlouho mluvit.
Today's match will be talked about for a long time. (locative — o dnešním zápase)
Watching jarní move through the cases
Because the masculine/neuter forms are the only ones that change, it helps to walk one masculine phrase through the cases and then confirm that the feminine really does stay put. Take hlavní vchod (the main entrance, masculine inanimate):
Hlavní vchod je z druhé strany budovy.
The main entrance is on the other side of the building. (nominative)
Sejdeme se u hlavního vchodu.
Let's meet by the main entrance. (genitive after u — hlavního)
Jdi rovnou k hlavnímu vchodu.
Go straight to the main entrance. (dative after k — hlavnímu)
Do budovy se dostaneš hlavním vchodem.
You get into the building through the main entrance. (instrumental — hlavním vchodem)
Now the feminine poslední tramvaj (the last tram): notice that poslední is identical in every line — it is the feminine column doing nothing at all.
Poslední tramvaj jede ve čtvrt na jednu.
The last tram leaves at a quarter past midnight. (nominative — poslední)
Bohužel jsme nestihli poslední tramvaj.
Unfortunately we missed the last tram. (accusative — still poslední)
Vrátil se domů až poslední tramvají.
He didn't get home until the last tram. (instrumental — still poslední)
Common Mistakes
The errors all come from one of two places: importing hard endings into the soft class, or doing the reverse and pushing the soft -í onto a hard adjective. Keep the two classes in separate boxes.
❌ Předpověď slibuje jarného počasí.
Incorrect — soft adjectives never take the hard -ého; the genitive is jarního.
✅ Předpověď slibuje jarní počasí.
The forecast promises spring weather.
❌ Žije teď v cizé zemi.
Incorrect — the feminine soft form never changes from -í: v cizí zemi.
✅ Žije teď v cizí zemi.
She lives in a foreign country now.
❌ To bylo opravdu krásní ráno.
Incorrect — krásný is a HARD adjective; don't lend it the soft -í. The neuter is krásné.
✅ To bylo opravdu krásné ráno.
That was a really beautiful morning.
❌ Vstávám každý den brzo, mám rád jarné ráno.
Incorrect — the soft neuter stays -í, it does not take the hard neuter -é: jarní ráno.
✅ Vstávám každý den brzo, mám rád jarní ráno.
I get up early every day; I love a spring morning.
❌ Na ulici jsem potkal cizí pána.
Incorrect — a masculine animate accusative takes -ího, just like the hard type takes -ého: cizího pána.
✅ Na ulici jsem potkal cizího pána.
I met a strange man on the street.
Key Takeaways
- The soft type (jarní) uses a single -í for masculine, feminine, and neuter in the nominative singular: jarní den, jarní noc, jarní ráno.
- It has only six distinct forms — jarní, jarního, jarnímu, jarním, jarních, jarními — far fewer than the hard type.
- The feminine column is invariable: always jarní. Only masculine/neuter add -ího, -ímu, -ím.
- Soft adjectives cluster around time and place (letní, zimní, ranní, dnešní, poslední, sousední) and relational meanings (cizí, hlavní, domácí); the -í ending is the giveaway.
- Never mix the boxes: no hard -ého on a soft adjective (jarního, not jarného), and no soft -í on a hard one (krásné ráno, not krásní ráno).
