You already know how to build a superlative — synthetic -ast / -aste, the umlaut -st, or analytic mest (see the comparison pages). This page is about how to use it: where it sits in the sentence, which ending it takes, and which little words frame it. The central fact, and the one English speakers most often get wrong, is that Swedish has two superlative shapes depending on whether the adjective sits in front of a noun or stands on its own — and the standalone form is the bare one, the opposite of English, which keeps "the" everywhere.
Attributive superlatives are definite: -aste after den/det/de
When a superlative sits in front of a noun, the whole phrase is definite. Swedish marks that definiteness in two places — the free article den / det / de before the adjective, and the -aste ending on the adjective itself — and the noun takes its definite suffix too. This is the same double-definiteness machinery that any definite adjective phrase uses (see Double Definiteness), and the superlative is no exception.
| Gender / number | Article | Adjective | Noun | Example |
|---|---|---|---|---|
| common sg. | den | -aste | -en | den största staden |
| neuter sg. | det | -aste | -et | det högsta berget |
| plural | de | -aste | -na | de billigaste bilarna |
Det högsta berget i Sverige heter Kebnekaise.
The highest mountain in Sweden is called Kebnekaise. det + högsta + berget — full definite superlative.
Vi tog den billigaste lägenheten vi kunde hitta.
We took the cheapest flat we could find. den billigaste lägenheten — article, -aste, noun suffix.
De äldsta husen i byn är från 1700-talet.
The oldest houses in the village are from the 18th century. de + äldsta + husen, plural definite.
Predicative superlatives are bare: -ast, no article
Now the contrast that catches English speakers. When the superlative does not sit in front of a noun but stands alone after vara ("be"), bli ("become"), or in an answer, Swedish uses the bare -ast form — no den/det/de, no -e ending. English keeps "the": He is *the oldest. Swedish drops everything: Han är äldst.*
Av alla i klassen är Anna äldst.
Of everyone in the class, Anna is the oldest. Bare äldst — NOT 'den äldsta', because it stands alone after 'är'.
Vilket berg är högst?
Which mountain is highest? Predicative högst, bare form — the standard way to ask.
Den här bilen är störst, men den där är snabbast.
This car is biggest, but that one is fastest. Both predicative superlatives stay bare: störst, snabbast.
The logic: the bare superlative is functioning like a predicate adjective, simply ascribing a top-of-scale quality to the subject. It is not picking out a particular noun ("the X one"), so there is no noun for the definite machinery to attach to. Compare:
| Attributive (picks out a noun) | Predicative (stands alone) |
|---|---|
| Det är den högsta byggnaden. "It's the tallest building." | Byggnaden är högst. "The building is tallest." |
| Hon är den äldsta systern. "She's the oldest sister." | Hon är äldst. "She is oldest." |
There is a subtlety worth flagging honestly: you can say Han är den äldsta — but then you mean "He is the oldest one," with an implied or elided noun, picking him out of a group as the member with that property. The bare Han är äldst simply ranks him at the top of the scale. In practice, for plain "he is the oldest," the bare form is what Swedes say.
"Of all", "in the world": the av / i frame
English uses "of" and "in" to bound a superlative — the oldest *of all, the tallest **in the world. Swedish uses *av for "of (a group)" and i for "in (a place/domain)" — crucially never än ("than"). Än belongs to the comparative; pairing it with a superlative is a classic transfer error.
Han är äldst av alla i familjen.
He is the oldest of all in the family. av alla = 'of all'; än would be wrong here.
Det är det högsta tornet i världen.
It's the tallest tower in the world. i världen = 'in the world'.
Vilken av rätterna är godast?
Which of the dishes is best? av rätterna frames the comparison set.
The absolute superlative: "a most peculiar story"
Finally, a use that is not comparison at all. The superlative — usually högst ("highly") or ytterst ("extremely") used adverbially — can intensify an adjective without ranking anything against anything. English does the same with "a most peculiar story," where "most" means "very," not "more than others." This register is (formal) to (literary); in casual speech you would just say mycket ("very").
Det var en högst märklig historia.
It was a most peculiar story. högst = 'highly/most' as an intensifier, not a real superlative — (formal/literary).
Saken är ytterst känslig.
The matter is extremely sensitive. ytterst as an absolute superlative intensifier — (formal).
Jag är högst tveksam till förslaget.
I am most doubtful about the proposal. högst tveksam = 'highly doubtful', intensifying not comparing — (formal).
Common Mistakes
❌ Berget är det högsta.
Incorrect — when 'highest' stands alone after 'är', use the bare form, not the definite one.
✅ Berget är högst.
The mountain is highest. Predicative = bare högst.
❌ Han är den äldsta än alla.
Incorrect — wrong on two counts: predicative should be bare, and 'than' must be av/i, not än.
✅ Han är äldst av alla.
He is the oldest of all.
❌ Det är högst berget i Sverige.
Incorrect — before a noun the superlative needs the definite frame: det + -aste + suffix.
✅ Det är det högsta berget i Sverige.
It's the highest mountain in Sweden.
❌ Stockholm är störst än alla städer.
Incorrect — a superlative takes av/i, never än; än is for comparatives.
✅ Stockholm är störst av alla städer.
Stockholm is the biggest of all cities.
❌ den högst byggnaden
Incorrect — the attributive (before-noun) superlative needs -aste, not the bare -st.
✅ den högsta byggnaden
the tallest building. Attributive = -aste (here -sta), bare -st is predicative only.
Key Takeaways
- Attributive (before a noun): definite frame — den/det/de
- -aste
- the noun's definite suffix (den största staden, det högsta berget, de billigaste bilarna).
- -aste
- Predicative (standing alone after vara/bli or as an answer): the bare -ast/-st form, no article — Berget är högst, Han är äldst. English keeps "the" here; Swedish drops it.
- Han är den äldsta exists but means "the oldest one" (a noun is implied); plain "he is the oldest" is the bare Han är äldst.
- Bound a superlative with av ("of" a group) or i ("in" a place) — never än, which belongs to the comparative.
- The absolute superlative (en högst märklig historia, ytterst känslig) intensifies rather than ranks, and is (formal/literary); casual speech uses mycket.

- Comparison: OverviewA2 — The big picture of comparing adjectives in Swedish: most use synthetic endings (-are for the comparative, -ast for the superlative, snabb → snabbare → snabbast), a smaller set uses periphrastic mer/mest (mer intressant, mest komplicerad), and the superlative has both an indefinite (-ast) and a definite (-aste) form.
- Regular Comparison (-are, -ast)A2 — The default Swedish comparison: add -are for the comparative (snabb → snabbare), -ast for the superlative (snabbast), and -aste before a definite noun (den snabbaste); 'than' is än, -el/-er/-en stems syncopate (vacker → vackrare), and the comparative never changes for gender or number.
- av (of, by) and PossessionB1 — The preposition av does the work English splits across several 'of' uses: it marks the agent of a passive ('by': målad av Anna), the material or part of a whole (gjord av trä, en del av kakan), and is locked into many fixed verb combinations (bestå av, leva av). Crucially, av is NOT the default translation of 'of' — Swedish routes 'of' three ways: the -s genitive for possession (Annas bok), av for partitive/material/agent, and på for intrinsic attributes (färgen på bilen).
