Weak & Strong Noun Declension

Weak vs strong noun declension patterns — the two main systems of Icelandic nouns

Learning Goal

Can distinguish weak and strong noun declension patterns and apply basic case endings

Exam Skills:VISC-A1

Look at these examples. Can you spot the grammar pattern?

Ég sé marga hesta.

I see many horses.

Ég gef konunni penna.

I give the woman a pen.

Bækur eru á borðinu.

Books are on the table.

Pay attention to the highlighted parts. What do they have in common?

Íslensk nafnorð fylgja tveimur meginbeygingarmynstrum:

Sterk beyging (strong — endingar breytast mikið):

Fallhestur (kk.)bók (kvk.)land (hk.)
Nf.hesturbókland
Þf.hestbókland
Þgf.hestibóklandi
Ef.hestsbókarlands
Nf. ft.hestarbækurlönd

Veik beyging (weak — endingar meira reglulegar):

Fallpenni (kk.)kona (kvk.)hjarta (hk.)
Nf.pennikonahjarta
Þf.pennakonuhjarta
Þgf.pennakonuhjarta
Ef.pennakonuhjarta
Nf. ft.pennarkonurhjörtu

Meginregla: Veik nafnorð hafa svipaðar endingar í öllum föllum (penna/penna/penna). Sterk nafnorð hafa mismunandi endingar og oft hljóðbreytingar (bók → bækur, land → lönd).

Apply this grammar in A1 course exercises

Practice Exercises
Applying strong declension to weak nouns or vice versa. Must memorize which class each noun belongs to. 🇬🇧 English speakers: English has no declension — all this is new. Weak nouns are easier to start with.

Ég sé marga hesta.

I see many horses.

Hesta = accusative plural of hestur (strong). Strong: hestur→hest→hesti→hests (sg), hestar→hesta→hestum→hesta (pl).

Ég gef konunni penna.

I give the woman a pen.

Konunni = dative definite of kona (weak f.). Penna = accusative of penni (weak m.). Both weak: regular endings.

Bækur eru á borðinu.

Books are on the table.

Bækur = nominative plural of bók (strong f.) — vowel changes: ó→æ (i-umlaut). Strong nouns often change their stem vowel.
