Indeclinable adjectives

Unlike most Swedish adjectives, indeclinable adjectives never change their form to match the gender (en/ett) or number of the noun they describe.

Vowel endings (redo, extra, rosa)

Many adjectives ending in a vowel (like -a or -o) are indeclinable. Notice how rosa (pink) stays exactly the same whether it describes a singular or plural noun:

Do you want pink cotton candy?
Vill du ha rosa sockervadd?
I like the pink tickets.
Jag tycker om de rosa biljetterna.

The words extra (extra) and redo (ready) follow the same pattern:

We want extra tickets, but they are not free.
Vi vill ha extra biljetter, men de är inte gratis.
We are ready for the amusement park.
Vi är redo för nöjesparken.

Consonant and -s endings (gratis, fel, lagom)

Adjectives ending in -s, such as gratis (free), skip the normal declension rules:

The ticket to the carousel is free today.
Biljetten till karusellen är gratis idag.

Some adjectives ending in a consonant also ignore the rules. Fel means "wrong," and the famously Swedish lagom means "just the right amount" or "just right":

You are standing in the wrong queue for the roller coaster.
Du står i fel kö till bergochdalbanan.
The carousel is neither fast nor slow, it is just right.
Karusellen är varken snabb eller långsam, den är lagom.
