Grammatical Gender: en and ett

Every Swedish noun belongs to one of two genders, and which one is the most consequential single fact you store about a noun — because gender quietly controls the article in front of it, the definite ending glued to its back, and the form of any adjective that describes it. English has no grammatical gender at all (we lost it around 800 years ago), so this is a genuinely new mental slot you have to open for every word. This page gives you the honest picture: how the two genders split, the few places where you can predict gender, and the much larger territory where you simply have to memorise it.

The two genders

The two genders are common gender (Swedish utrum) — the en-words — and neuter (neutrum) — the ett-words. The names "en" and "ett" come from the indefinite article each takes ("a/an"): you say en bil but ett hus. Common gender is by far the larger class: roughly three out of four nouns are en-words, and about one in four is an ett-word.

The honest truth: gender is mostly arbitrary

Here is the thing most courses soften and you should hear plainly: for the majority of nouns, gender is not predictable from meaning or form. A bil (car) is an en-word; a tåg (train) is an ett-word — and nothing about cars and trains explains the difference. A stol (chair) is en, a bord (table) is ett. The split is largely a historical accident: the old language had three genders (masculine, feminine, neuter), the masculine and feminine merged into today's common gender, and the result is a roughly 75/25 division that no longer tracks anything you can see or reason about.

So the realistic strategy is the one good learners adopt early: learn the article as part of the word. Store ett bord, not bord. Store en stol, not stol. The two or three letters of the article are cheap to memorise alongside the noun and expensive to bolt on afterwards, because by then you have practised the word wrong dozens of times.

The tendencies that genuinely help

A handful of patterns are reliable enough to lean on. They will not make you right every time, but they shift the odds well above a coin flip.

Nouns ending in unstressed -a are almost always en. This is the strongest single cue in the language. Flicka, gata, kvinna, blomma, ros... a (any noun whose dictionary form ends in -a) is overwhelmingly common gender. (The plural of these is the -or class — see Plural Class 1: -or.)

Most people and most animals are en-words. En man, en kvinna, en läkare, en hund, en katt, en häst. Living, animate beings tilt heavily toward common gender — a residue of the old masculine/feminine system. (Note: a few familiar exceptions exist, e.g. ett barn "a child," ett lejon "a lion," ett djur "an animal" — animacy is a tendency, not a law.)

Many borrowed and abstract nouns are neuter, and many short, "thing-like" words are too. Loanwords ending in a consonant frequently land in the ett class (ett system, ett problem, ett museum, ett kafé), and a good number of everyday concrete neuters are short ett-words (ett hus, ett bord, ett rum, ett glas, ett ben). These are tendencies, not rules — en buss, en film, en kostym are common-gender loans — but "if it's a short, abstract or borrowed thing, suspect ett" is a useful prior.

For the practical decision procedure — how to weigh these cues when you meet a brand-new word — see Choosing: en vs ett.

Why gender matters: it controls three things

Gender would be a harmless label if it stayed put on the noun. It does not — it agrees outward onto the words around the noun. Get the gender wrong and the error ripples into three places at once.

1. The indefinite article. Common gender takes en, neuter takes ett. This is the most visible consequence and the one beginners get wrong most.

2. The definite ending. En-words take -en; ett-words take -et. So the gender you stored picks the "the" suffix: bil → bilen, but hus → huset. (Full rules on The Definite Singular.)

3. The adjective. An adjective describing a neuter noun adds a -t. This is the famous neuter-t agreement: röd "red" becomes rött before an ett-word. So you say en röd bil but ett rött hus. There is no analogue in English — red never changes — and forgetting the -t is an instant marker of a non-native.

This is the deeper reason memorising gender pays off: it is not one fact but the trigger for a chain of agreements. The mechanics of the -t form are on The Neuter -t on Adjectives.

The classic English-speaker error: defaulting to en

Because en-words are three times as common, learners develop a habit of just saying en for everything — and because they are right 75% of the time, the habit feels safe and goes uncorrected for months. It is the single most persistent gender error. The fix is not to default; it is to mark ett-words actively in memory, since they are the minority you'll otherwise miss. When you learn a new neuter noun, flag it: ett hus, ett bord, ett problem. Treat the ett as the surprising, must-remember part.

Common Mistakes

Key Takeaways

• Swedish has two genders: common-gender en-words (~75%) and neuter ett-words (~25%).
• For most nouns gender is arbitrary and must be memorised — always learn the article with the word (ett bord, not bord).
• Real tendencies cut the guesswork: unstressed -a → en (strongest cue), most people/animals → en, many abstract/borrowed/short "thing" words → ett.
• Gender controls three things: the article (en/ett), the definite ending (-en/-et), and the adjective's neuter -t (rött).
• The classic error is defaulting to en; counter it by actively flagging the minority ett-words.
