Adjective Endings
Danish adjectives change form to match the noun they describe. There are three forms based on gender, number, and definiteness.
The three forms
Base form — with en-words (indefinite)
en stor bil — a big car
-t form — with et-words (indefinite)
et stort hus — a big house
-e form — plural or definite
store biler — big cars, den store bil — the big car
Examples
en-word
et-word
Plural/def.

The -e rule is the most common
Whenever the noun is definite (den store bil) or plural (store biler), the adjective takes the -e ending. This covers most situations in everyday speech.
