Vowel Length and Spelling
rum become rummet?Swedish vowels are long or short, and the spelling usually tells you which. This rule also explains why consonants double when words inflect, which you met in En, Ett, and the Definite Noun.
Why are these different words?
The Core Rule
In a stressed syllable, either the vowel is long or the consonant after it is long. Not both, not neither.
Reading rule: one consonant after the vowel usually means a long vowel; a double consonant or consonant group usually means a short vowel.
Why Inflection Doubles Consonants
The spelling follows the sound when endings are added. A short stressed vowel keeps its double consonant marker:
And m/n have a spelling quirk: they are often written single at the end of a word even after a short vowel (rum, man, kom), so the doubling only becomes visible when an ending follows.
Minimal Pairs Worth Hearing
vit / vitt white (common / neuter)
sil / sill strainer / herring
mata / matta feed / carpetNotice vit -> vitt: the neuter -t from Describing Nouns creates a spelling with a short-vowel look. Listen to the dictionary audio rather than guessing the vowel from the base form.

| vowel + single consonant | long | tak, väg |
| vowel + double consonant | short | tack, vägg |
final m/n after short vowel | often written single | rum -> rummet |
