In English, an adjective never changes: a big car, a big house, big cars — big is big every time. Norwegian adjectives, by contrast, agree with their noun. There are only three endings to learn, which is mercifully few, but you have to apply them every time — and, crucially, you have to apply them even after the verb å være (to be), where English speakers' instincts go completely silent. This page covers the core indefinite agreement: the bare form, the -t form, and the -e form.
The three forms
The whole system fits in one table. Take an adjective like stor (big) and watch it shift:
| Context | Form | Example | Gloss |
|---|---|---|---|
| Masculine singular | stor (bare) | en stor bil | a big car |
| Feminine singular | stor (bare) | ei stor hytte | a big cabin |
| Neuter singular | stort (-t) | et stort hus | a big house |
| Plural (any gender) | store (-e) | store biler / hus | big cars / houses |
Three rules, then:
- Masculine and feminine singular → bare form (the dictionary form): en stor bil, ei stor hytte.
- Neuter singular → add -t: et stort hus.
- All plurals → add -e, regardless of gender: store biler, store hus.
Vi har en stor hage og et lite hus.
We have a big garden and a small house. (bare 'stor' with masculine; '-t' on neuter 'lite' is irregular — see below)
Det var et stort problem, men vi løste det.
It was a big problem, but we solved it. (neuter -t)
De bygde store hus langs hele fjorden.
They built big houses all along the fjord. (plural -e)
Attributive and predicative — both agree
This is the point where English instincts fail. A Norwegian adjective agrees in both positions:
- Attributive (in front of the noun): en fin dag, et fint hus, fine dager.
- Predicative (after å være, å bli, å se ut): dagen er fin, huset er fint, dagene er fine.
In English, the predicate adjective is invariable: "the day is nice, the houses are nice" — no change for the plural. In Norwegian, the predicate adjective takes the very same agreement endings as the attributive one. So "the houses are nice" is husene er fine, with the plural -e.
| Attributive | Predicative | |
|---|---|---|
| Masc. sing. | en fin dag | dagen er fin |
| Fem. sing. | ei fin hytte | hytta er fin |
| Neut. sing. | et fint hus | huset er fint |
| Plural | fine dager | dagene er fine |
Huset er stort, men hagen er liten.
The house is big, but the garden is small. (predicate 'stort' takes -t; 'liten' is irregular)
Barna er snille og greie.
The children are kind and easy-going. (predicate plural -e — English has no plural marking here)
Suppa var god, men brødet var litt tørt.
The soup was good, but the bread was a bit dry. (neuter 'tørt' with -t)
The neuter -t and its spelling effects
Adding -t for the neuter is usually as simple as it sounds — fin → fint, grei → greit, stor → stort. But two spelling things happen at the join that you should expect:
A final consonant may double. When the adjective ends in a stressed short vowel + single consonant, that consonant doubles before -t in some words — though more often the effect is the reverse (see grønn below). The cleanest case to remember is the vowel-final adjectives that double the t: ny → nytt (new), fri → fritt (free), blå → blått (blue).
Vi har kjøpt et helt nytt kjøleskap.
We've bought a completely new fridge. (ny → nytt, double t)
A double consonant may shorten. Adjectives ending in a double consonant often drop one before -t: grønn → grønt (green), sann → sant (true). So "a green house" is et grønt hus, not "grønnt."
Det er et grønt teppe i stua.
There's a green rug in the living room. (grønn → grønt)
Er det sant at dere flytter til Bergen?
Is it true that you're moving to Bergen? (sann → sant)
These adjustments have their own detail page; for now, just know that the neuter -t is not always a clean add — sometimes a letter doubles, sometimes one drops. The plural -e and the bare form do not cause such effects, so the -t is the one to watch.
A worked example: fin across the board
To lock the pattern in, here is fin (nice / fine) in every slot, attributive and predicative:
| Noun phrase | Predicate version | Gloss |
|---|---|---|
| en fin bil | bilen er fin | a nice car / the car is nice |
| ei fin jente | jenta er fin | a nice girl / the girl is nice |
| et fint hus | huset er fint | a nice house / the house is nice |
| fine biler | bilene er fine | nice cars / the cars are nice |
For et fint vær i dag! Skal vi gå en tur?
What lovely weather today! Shall we go for a walk? (neuter 'vær' → 'fint')
Skoene dine er kjempefine — hvor kjøpte du dem?
Your shoes are really nice — where did you buy them? (plural predicate 'fine')
Common Mistakes
No agreement at all. Treating the adjective as invariable, English-style, leaves the neuter and plural unmarked.
❌ Vi bor i et stor hus.
Incorrect — neuter singular needs -t: 'et stort hus'.
✅ Vi bor i et stort hus.
We live in a big house.
Forgetting predicate agreement. After er, the adjective still agrees — especially in the plural, where English has nothing.
❌ Husene er stor.
Incorrect — plural subject needs -e: 'husene er store'.
✅ Husene er store.
The houses are big.
❌ Barna er snill.
Incorrect — plural predicate needs -e: 'barna er snille'.
✅ Barna er snille.
The children are kind.
Adding -t to a plural. The -t belongs to neuter singular only; plurals always take -e.
❌ Det er mange stort hus her.
Incorrect — plural takes -e, not -t: 'mange store hus'.
✅ Det er mange store hus her.
There are many big houses here.
Mis-spelling the neuter -t. Forgetting to double (nytt) or to shorten (grønt) at the join.
❌ et ny kjøkken / et grønnt eple
Incorrect — 'ny → nytt' (double t), 'grønn → grønt' (single t).
✅ et nytt kjøkken / et grønt eple
a new kitchen / a green apple.
Putting -t on a masculine or feminine singular. The bare form is correct for masculine and feminine; only neuter takes -t.
❌ Det var en fint dag.
Incorrect — masculine singular is bare: 'en fin dag'.
✅ Det var en fin dag.
It was a nice day.
Key Takeaways
- Bare form for masculine/feminine singular, -t for neuter singular, -e for every plural.
- Adjectives agree predicatively too (husene er store) — the error English speakers make most.
- The neuter -t can double a vowel-final adjective (ny → nytt) or shorten a double consonant (grønn → grønt).
- This page is the indefinite pattern; the definite form (which adds -e even in the singular: det store huset) and the irregular adjectives (liten, blå, bra) live on their own pages.

- The Definite Form: den store bilenA2 — After den/det/de, a demonstrative, a possessive, or a genitive, a Norwegian adjective takes the invariable definite -e regardless of gender or number — so the neuter loses its -t (det STORE huset, never 'det stort huset'), and possessives trigger it too (min store bil).
- Irregular Adjective AgreementB1 — The adjectives that break the -/-t/-e pattern — the suppletive liten/lita/lite/små/lille, the -ig/-lig and -sk adjectives that refuse the neuter -t (et viktig møte, et norsk flagg), the -el/-en/-er syncope (gammel → gamle), and the indeclinable class (bra, ekte, moderne, rosa) that never changes at all.
