Swedish spelling is reasonable but not simple. There are rules — but they have exceptions, and the exceptions rarely have logic. This article walks through the most important rules a 7–9-year-old meets at school, with examples they actually write at primary level.
At Kluriko several spelling games in the Learning Games train exactly these rules — but understanding starts with them seeing the patterns. Lay these rules down slowly, one at a time, and you avoid hopelessness in them.
Rule 1: Double consonant after short vowel
When a vowel is short (pronounced quickly) it's often followed by a double consonant.
- Bil (car) → bilen (long i, one l)
- Bill (Bill) → Billen (short i, two l's)
- Sak (thing) → saken (long a)
- Säck (sack) → säcken (short ä, two c's)
It's not always obvious to the ear. But they can listen. Säng (short ä, two ng-signs) vs bena (long e, one n). Two letters = short vowel. One = long.
Rule 2: M before P and B
Before P and B you always write M, never N. Lampa, kompis, kompass, bomb, kombination. One of the few no-exceptions rules in Swedish. A 7-year-old can learn it in five minutes.
Play "find M before P or B" in a book. They get the pattern quickly.
Rule 3: Tj-, Sj-, Sk-sounds — tricky spelling
These are spelled multiple ways (sk, skj, stj, sj, ch). It's not rule-based — it's memorise per word.
- TJ-sound: tjur, kär, kil, köpa (k+vowel), tjock.
- SJ-sound: sjö, sjunga, ski, schäfer, station, journal.
- SK-sound: sko, skola, ski (distinguished from sj only in context).
Solve this with fridge lists, not rules. They read, see the spelling, memorise.
Rule 4: K vs C
K is more common. C is rare and almost always a loanword (cancer, central, cement, cykel).
- Before a, o, u, å it's usually k for the k-sound: kall, kort, kund, kåk.
- But c shows up in loans: cancer, citron.
- Before e, i, y, ä, ö, c can be an s-sound: cement, citron, cykel.
A hard rule. Save for after year 2.
Rule 5: Å, Ä, Ö are their own letters
Not "a with a ring", not "ä is a with dots". They're their own letters in the alphabet, the last three. They should know this from age 6.
Spelling lists: "Å, Ä, Ö" always come last. Phone books, dictionaries.
Rule 6: Bigger and smaller — ä vs e
Many Swedish words have e that sounds like ä, or vice versa. They're often unsure.
- Skäl (ä-sound, ä-spelling), but sken (e-sound, e-spelling)
- Träffa (ä-sound, ä-spelling), but trefärgad (e-sound, e-spelling)
This takes years to settle. Volume reading is the recipe.
Rule 7: T-consonant and D-consonant
T and D sound almost alike but spell differently. Lite always with t. Lida always with d. Memory, not rule.
Rule 8: S-consonant and Z-consonant
Z is rare in Swedish. Found in a few loans (pizza, zoo). In most Swedish words it's S, not Z. They shouldn't spell "saker" with Z.
Rule 9: Other signs
- Ck after a short vowel: gick, tjock, vacker.
- Tion-ending: station, nation. Pronounced "schon", spelled "tion".
- Ng at the end of words: säng, ring. Not "nn".
- X is rare, mostly loanwords.
When do explicit rules begin?
Year 1: no rule teaching. Phonetic learning.
Year 2: "m before p and b" is introduced.
Year 3: doubling, sj/tj/sk sounds start being discussed.
Year 4: spelling rules become part of Swedish lessons.
At home: start with m-before-p-and-b at 6–7. The rest comes naturally.
Common mistakes in their writing
- "Lampa" written "Lanpa" — m-before-p rule missing
- "Säng" written "Sänng" or "Sing" — ng-sound
- "Tjock" written "Tjok" — doubling missing
- "Sjö" written "Schö" — sj-sound misspelling
- "Cement" written "Sement" — c/s confusion
How Kluriko helps
Kluriko Learning Games have spelling games where they practise doubling, m-before-p-and-b, and the sj/tj sounds in context. The games are more effective than worksheets because they reward right answers and repeat.
