Questions & Answers about Jag tror att det är ett slags tilltugg.
Why is it ett slags here? Does the ett agree with tilltugg?
In strict grammar, the ett belongs to the fixed phrase ett slags (a kind of), which comes from the ett-word slag (kind/type). Traditionally, you always use ett slags, even if the following noun is an en-word. It just so happens that tilltugg is also an ett-word (ett tilltugg). In everyday speech, many Swedes bend the rules and say en slags if an en-word follows, but ett slags remains the most grammatically correct choice in all situations.
Is there a difference between using ett slags and en sorts here?
No, they mean the exact same thing and are used interchangeably to mean "a kind of" or "a sort of". Just remember that sort is an en-word, so its fixed phrase is always en sorts. You could easily rewrite this sentence as: Jag tror att det är en sorts tilltugg.
Why does the sentence use tror instead of tycker or tänker for "believe/think"?
This is a great refresher! You use tror when you are expressing a belief or a guess about a fact that you aren't completely sure about—like guessing what type of food is on a plate. You use tycker for subjective opinions (e.g., "I think it tastes good"), and tänker for the active cognitive process of using your brain.
