Questions & Answers about Konceptet är nytt, men köttet är lite rått.
Why do ny and rå get a double -tt at the end here?
Because they are describing the neuter nouns konceptet and köttet. When a Swedish adjective ends in a stressed long vowel, like ny (new) or rå (raw), it takes a double -tt in the neuter singular form to become nytt and rått.
Does adding -tt to ny and rå change how they are pronounced?
Yes! In the base forms ny and rå, the final vowel is long. When you add the double consonant -tt, that vowel becomes short. So the vowel sounds in nytt and rått are pronounced much faster and sharper than in their base forms.
Is rått the same word as the animal rat?
They can look confusingly similar, but no. The word rått here is simply the neuter form of the adjective rå (raw). The Swedish noun for a rat is an en-word, en råtta.
Since konceptet and köttet are in the definite form, shouldn't the adjectives take the definite -a ending?
