Invariable adjectives (plastic, roze, gratis)

Invariable Adjectives

In Dutch, adjectives placed directly in front of a noun usually get an -e ending. However, some adjectives are invariable and never change form, regardless of the noun's gender or article.

This applies to many modern loanwords and adjectives ending in a vowel (like -a, -o, -i, or -y).

We are handing out a retro keychain.
We zijn een retro sleutelhanger aan het uitdelen.
The client wants a trendy promotional gift with a logo.
De klant wil een trendy relatiegeschenk met een logo.

Notice how the regular adjective (mooie) takes its usual -e ending, but the invariable color (kaki) does not:

Yesterday we ordered beautiful khaki T-shirts.
Gisteren hebben we mooie kaki T-shirts besteld.

Colors and Styles

Words like blanco (blank), uniseks (unisex), and lila (lilac) follow the exact same pattern.

They are giving away a blank mug without an imprint.
Zij geven een blanco mok zonder opdruk weg.
This unisex clothing is quite cheap.
Deze uniseks kleding is tamelijk goedkoop.

Even when used with definite articles (de or het)—where you would normally expect an -e ending on a standard adjective—invariable adjectives stand their ground.

Are we choosing the khaki bag or the lilac bag?
Kiezen we de kaki tas of de lila tas?
The pink logo fits perfectly on the blank mug.
Het roze logo past perfect op de blanco mok.
