Definite plural nouns (-nir, -nar, -in)

To make plural nouns definite ("the boats"), attach the definite article directly to the end of the indefinite plural form. The suffix depends on the noun's gender:

GenderIndefinite PluralDefinite PluralSuffix

Feminineflöskurflöskurnar-nar
Neuterblómblómin-in
Neuter (vowel)trétrén-n

Masculine: -nir

For masculine nouns, add -nir.

The boats are large.
Bátarnir eru stórir.
The birds are singing a lot today.
Fuglarnir syngja mikið í dag.

Feminine: -nar

For feminine nouns, add -nar.

The bottles and the cups are inside.
Flöskurnar og bollarnir eru inni.
The shoes are old but the sweaters are new.
Skórnir eru gamlir en peysurnar eru nýjar.

Neuter: -in and -n

Neuter nouns do not change in the indefinite plural—a bare neuter noun like blóm means both "flower" and "flowers". To make it definite, add -in. If it ends in a vowel, add -n.

Are the flowers beautiful?
Eru blómin falleg?
The trees are very big.
Trén eru mjög stór.
The apples are not good today.
Eplin eru ekki góð í dag.

Dýrin og fuglarnir sofa núna.
The flowers and the trees are outside.
Blómin og trén eru úti.
