Singular adjective agreement

Matching Adjectives to Nouns

In Icelandic, descriptive words (adjectives) change their endings to match the grammatical gender (masculine, feminine, or neuter) of the noun they describe.

  • Masculine adjectives often end in -r, -ur, or -ll.
  • Feminine adjectives usually drop the masculine ending. Sometimes the core vowels change as well, such as gamall becoming gömul.
  • Neuter adjectives typically end in -t. Adjectives ending in -ill take -ið in the neuter (such as lítill becoming lítið).

Here is how common adjectives change across the three genders:

Here are masculine adjectives in action:

This is a big car.
Þetta er stór bíll.
This is a small dog.
Þetta er lítill hundur.

Notice how the adjective changes when describing feminine nouns:

This is a new book.
Þetta er ný bók.
Is this an old book?
Er þetta gömul bók?

And here are the neuter forms:

This is an old house.
Þetta er gamalt hús.
Is this a big table?
Er þetta stórt borð?

Adjectives After "To Be"

An adjective must still match the noun's gender even when it is separated from the noun by the verb vera (to be).

The woman is old.
Konan er gömul.
The girl is new here.
Stelpan er ný hér.

When describing multiple things in one sentence, make sure each adjective agrees with its respective noun. You can connect contrasting descriptions using en (but) or og (and).

The boy is big but the girl is small.
Strákurinn er stór en stelpan er lítil.
The child is big but the cat is small.
Barnið er stórt en kötturinn er lítill.
The woman is old but the teacher is new.
Konan er gömul en kennarinn er nýr.
