Common Spelling Pitfalls | Swedish Grammar

This page gathers the spelling errors that catch English speakers most often and do not have a dedicated page of their own — and it does so around one organising idea worth stating up front: a surprising number of Swedish "spelling" mistakes are not really about letters at all, but about hearing. Swedish reduces hard in ordinary speech — och and att both come out as a little "å", det sounds like de, de and dem both sound like dom — so the learner faithfully writes down what they heard and lands on the wrong word. Recognising a mistake as a mishearing of reduced speech rather than a random slip is what lets you fix it for good. The big topics (compounds, the m/n rule) have their own pages; here are the rest.

och vs att: two words, one reduced sound

This is the most consequential pair on the page. och means "and"; att means "to" (before an infinitive) or "that" (introducing a clause). They are unrelated words doing completely different grammatical jobs — but in casual speech they collapse onto nearly the same reduced vowel, a short "å" sound. och is often just [ɔ], and att, especially the infinitive marker, is frequently reduced to [ɔ] / "å" too. So your ear hears "å ... å ..." and you have no acoustic clue which word to write.

The fix is grammatical, not phonetic: ask what the word is doing.

Linking two equal things (nouns, clauses, phrases)? → och (and).
Standing before a verb in its base form? → att (the infinitive marker "to").
Introducing a subordinate clause after verbs like säga, tro, veta, hoppas? → att (the conjunction "that").

Jag vill fika och prata.

I want to have coffee and chat. — och links the two infinitives 'fika' and 'prata'.

Jag glömde att ringa.

I forgot to call. — att is the infinitive marker before ringa.

Hon sa att hon kommer sent.

She said that she's coming late. — att is the conjunction 'that' introducing the clause.

Det är svårt att veta vad man ska göra och säga.

It's hard to know what to do and say. — att before the infinitive veta; och linking göra and säga, in one sentence.

💡

The test that never fails: can you replace the word with "and"? If yes, it's och. Is it sitting right before a base-form verb, or after a saying/thinking verb? Then it's att. Never decide by sound — in speech they are nearly identical, which is exactly why the error exists. The full decision guide is on och vs att.

This belongs to a whole family of reduction-driven errors. The choice itself — which word fits where — is covered in depth on och vs att; here the point is to recognise that the spelling error is born in the pronunciation.

de vs dem vs dom: the written/spoken split

A second reduction trap, and one even native writers struggle with. In speech, almost everyone says dom [dɔm] for both the subject pronoun de ("they") and the object pronoun dem ("them"). But standard writing still distinguishes them: de = they (subject), dem = them (object). Because the spoken dom covers both, learners cannot hear which to write, and many default to writing dom (which is accepted in very informal text but wrong in anything formal).

De bor i Malmö.

They live in Malmö. — de is the subject, written de even though it's said 'dom' (informal).

Jag känner dem väl.

I know them well. — dem is the object of känner, written dem (said 'dom').

De bjöd dem på middag.

They invited them to dinner. — de (subject) and dem (object) in one clause, both pronounced 'dom' in speech.

The reliable test mirrors English they vs them: if you would say they in English, write de; if you would say them, write dem. The complete strategy, including the dom-in-writing question, is on de, dem and dom. And note a near neighbour: det (it/that) is pronounced "de" [deː] — so the spoken "de" you hear is sometimes actually det. Three written forms (de, dem, det) hide behind two reduced spoken sounds.

Det är de som bestämmer.

It's they who decide. — det ('it', said 'de') and de ('they', said 'dom') in the same sentence: two different written words, two different reduced sounds.

ck, not kk and not k: marking a short vowel before k

Swedish doubles consonants to mark a short stressed vowel (see Double Consonants and Vowel Length) — but the letter k is special: its "doubled" form is written ck, never kk. So a short vowel before a k-sound is spelled ck, a long vowel before it stays single k, and kk simply does not occur in native Swedish words.

Short vowel → ck	Long vowel → single k
tack (thanks) [tak]	tak (roof / ceiling) [tɑːk]
lycka (happiness) [ˈlʏka]	vika (to fold) [ˈviːka]
rock (coat) [rɔk]	rok — not a word; cf. bok (book) [buːk]
flicka (girl)	fika (coffee break) [ˈfiːka]

So the doubling rule is alive and well for k — it just wears the disguise ck. Writing takk or lykka (English/Norwegian-Danish habits) is wrong; so is writing tak for "thanks", which gives "roof".

Tack så mycket för hjälpen!

Thanks so much for the help! — tack with ck, short a; tak (single k) would mean 'roof'.

Vilken lycka att se dig!

What a joy to see you! — lycka with ck marks the short y.

Ta på dig rocken, det är kallt.

Put your coat on, it's cold. — rock with ck (short o); contrast bok 'book' with a long vowel and single k.

💡

For the k-sound, the doubling rule still applies — it just looks different: short vowel → ck, long vowel → k, and kk is never written in native words. So 'thanks' is tack (short, ck) and 'roof' is tak (long, single k). If you catch yourself writing kk, it's almost certainly meant to be ck.

o or å for the same sound: a real ambiguity

Here is a place where Swedish spelling genuinely does not help you, and honesty serves better than a false rule. The letters o and å can both spell an [oː]/[ɔ] sound, and which one a given word uses is not predictable — you memorise it word by word. bo (to live), sol (sun), ord (word) use o; gå (to go), år (year), båt (boat) use å. There is no reliable phonetic cue; the o in sol and the å in mål can land very close in sound.

Solen skiner — vi tar båten till ön.

The sun is shining — let's take the boat to the island. — sol with o, båt with å, similar sounds, different letters: memorise per word.

Jag vill bo nära ett torg.

I want to live near a square. — bo with o; the long o here is the 'oo'-type [uː], a reminder that o has its own range too.

The safe move: when learning a new word, learn its spelling, not just its sound — note whether it is o or å the first time you meet it. And of course keep å, ä, ö fully distinct from a, o, u: dropping the ring or dots is never optional and usually produces a different word (mål "goal" vs mal "moth").

Vi äter middag klockan åtta.

We're having dinner at eight o'clock. — åtta with å; the ring is part of the word, not decoration.

A note on je-/ge- spellings

A smaller trap: the soft g before a front vowel sounds like j (a y-glide), so ge (to give) [jeː], gilla [ˈjɪla], gärna [ˈjæːɳa] all sound as if they start with j — and learners sometimes write je- for ge-. Trust the spelling: native words generally keep the g even though it has softened to [j]. Conversely, words genuinely spelled with initial j (jobba, ja, jul) keep the j.

Kan du ge mig saltet?

Can you give me the salt? — ge sounds like 'yeh' [jeː] but is written with g, not j.

Jag gillar verkligen det här jobbet.

I really like this job. — gillar (soft g, sounds like 'yillar') keeps its g; jobbet keeps its j.

Common Mistakes

❌ Jag vill fika å prata.

Incorrect — writing 'å' (or hearing the reduced sound) for och. The link between two verbs is och.

✅ Jag vill fika och prata.

I want to have coffee and chat.

❌ Hon sa och hon kommer sent.

Incorrect — confusing och and att. After 'said', the clause is introduced by att ('that'), not och ('and').

✅ Hon sa att hon kommer sent.

She said that she's coming late.

❌ Jag såg de igår på stan.

Incorrect — de is the subject form ('they'). As the object of såg, it must be dem ('them').

✅ Jag såg dem igår på stan.

I saw them in town yesterday.

❌ Tusen takk för maten!

Incorrect — kk never occurs in native Swedish; a short vowel before k is spelled ck: tack.

✅ Tusen tack för maten!

Thanks a lot for the meal!

❌ Vi tar batan till on.

Incorrect — dropping å and ö. The boat is båt → båten, the island is ö → ön; the marks are not optional and change the words.

✅ Vi tar båten till ön.

We'll take the boat to the island.

Key Takeaways

Many spelling errors are mishearings of reduced speech: och and att both sound like "å"; de and dem both sound like dom; det sounds like "de".
och vs att is decided by grammar, not sound — och = "and", att = "to" (before a verb) / "that" (after saying/thinking verbs).
de (they, subject) vs dem (them, object) follows English they/them; everyday speech says dom for both.
For the k-sound: short vowel → ck (tack, lycka), long vowel → single k (tak); kk never occurs.
o vs å for similar sounds is genuinely unpredictable — learn each word's spelling — and å, ä, ö are never optional (båt, ön, åtta).
