Hej igen!
I have already received a number of questions and I want to thank everyone for contributing to this blog! As we say in Swedish:
Frågar man inget, får man inget veta.
One reader wants to know the rules for constructing plural of the noun. His question is this:
“Can you do something on plurals, and how we know which ending to add to a word?
If you could have these for the indefinite and definite forms that would be very helpful! “
5 noun groups – declensions
The nouns in Swedish can be sorted into five different groups or “declensions” as we also can call them.
1. In the first declension we find en-words (nouns with gender en) that end with an -a. This is a quite large group with common words as:
en blomma
(a flower)
en lampa
(a lamp)
en kvinna
(a woman)
en flaska
(a bottle)
en väska
(a bag)
All words in this group will look like this in plural form:
blommor
lampor
kvinnor
flaskor
väskor
As you can see, what you need to do to create the plural form is removing the -a and ad -or. If you want to create the definite form (bestämd form), the flowers, the bottles, you ad -na. Now it looks like this:
blommorna
lamporna
kvinnorna
flaskorna
väskorna
2. In the second declension there are mainly one-syllable nouns with gender en. Common words that fit into this group are:
en bil
(a car)
en kopp
(a cup)
en hund
(a dog)
en stol
(a chair)
en säng
(a bed)
In this group we will also find a number of other nouns that ends with a unstressed -e, -el, -en, -er or -on. Some examples of these words are:
en pojke, en bulle
(a boy, a cinnamon roll)
en cykel, en fågel
(a bike, a bird)
en öken
(a desert)
en syster, en vinter
(a sister)
en morgon
(a morning)
This is what the words in the second group look like in plural form:
bilar
koppar
hundar
stolar
sängar
pojkar
bullar
cyklar
fåglar
öknar
systrar
vintrar
morgnar
So, you can see that the plural ending for this group is -ar. You might also have noticed already that the words with an unstressed -e, -el, -en, -er or -on loses the -e or -o in plural. For plural definite form we ad -na just like in the first declension. Then we end up with:
bilarna, kopparna, hundarna, stolarna, sängarna, pojkarna, bullarna, cyklarna, fåglarna, öknarna, systrarna, vintrarna and morgnarna
3. In the third declension there are words like en polis, en biljett and en telefon: and what do they have in common? Well they are all loan words as they originally come from another language. Many of the words in this group consists of several syllables. More examples:
en familj
( family)
en cigarett
(a cigarette)
en ingenjör
(an engineer)
To create the plural form of the nouns in this group we ad -er. Like this:
poliser
biljetter
telefoner
familjer
ingenjörer
Again, to create the definite form plural we ad -na at the end of the word. Like this:
poliserna
biljetterna
telefonerna
familjerna
ingenjörerna
The words are starting to get quite long now, right? 
It is also worth mentioning that some of the words in this group get a so called “omljud” in plural which means that they change vowel. This happens to words that we use on a daily basis:
en hand händer
(a hand)
en tand tänder
(a tooth)
en son söner
(a son)
en fot fötter
(a foot)
4. Ok, enough with the en-words! In the fourth declension are a number of ett-words. The second thing they have in common is that they all end with a vowel. Hurray! Finally a rule that is easy to remember! Common words in this group are for example:
ett äpple
(an apple)
ett knä
(a knee)
ett konto
(an account)
ett meddelande
(a message)
ett arbete
(a job)
To express the plural form of these nouns we simply ad -n which will make our examples from above look like this:
äpplen
knän
konton
meddelanden
arbeten
It is worthy of note that if you are not familiar with the Swedish plural rules, or think that äpple is an en-word, you might think that äpplen means “the apple”. To create the definite form plural out of the words in the fourth group we will have to ad -a so we get:
äpplena
(the apples)
knäna
(the knees, my knees)
kontona
(the accounts)
meddelandena
(the messages)
arbetena
(the jobs)
5. All right, one more group to go – the fifth declension. (By this time in a classroom you would have been in coma!) Luckily, the fifth group is the one that is the easiest to remember. The rule is simple: ett-words ending with a consonant. A few examples:
ett hus
(a house)
ett barn
(a child)
ett rum
(a room)
ett problem
(a problem)
ett år
Ok, so what do we have to do to turn these guys into plural form? The answer is:nothing! One might think that the Swedes ran out plural endings or something. Anyway, this is what our examples look like in plural:
hus
(houses)
barn
(children)
rum
(rooms)
problem
(problems)
år
(years)
To make definite form we ad -en. Like this:
husen
barnen
rummen
problemen
åren

Hi Sara!
Thanks for this useful guide. Can I just check with you, in point (2) above, you listed two “bilarna” words. Shouldn’t one of them be “bilar”?
Thanks very much!

Thanks for being so attentive Grace! You’re right
I have corrected that now. I guess even aSwedish teacher can be tired sometimes

Cool list! (yes, I’m a bit of a nerd)
I’m just thinking of the neuter words of the third(?) declension, the ones like “fängelse” and “batteri”, which I don’t find listed.

Hej Mikael!
Thank you for your input. There is nothing wrong with being a nerd
“Ett batteri” does, just like you say, belong to the third declension. Other words in that category are “bageri”, “kalori” and “idé”. The thumb rule here is that these words are en- and ett-words ending with -eri, -ori and -é. The plural form of “ett fängelse”is fängelser and should also be listed in the third declension.

Wow! Thank you a lot indeed for this wonderful list of the word endings. After Bergman’s films I started to be interested in Swedish lung. so now I’ll use your wonderful list.
Thank you! Ann
