Questions & Answers about Jag tycker den första ledtråden är väldigt logisk.
Where exactly is the word att (that) omitted in this sentence?
It is dropped right after the main verb: Jag tycker (att) den första ledtråden... Just like in English ("I think that..."), leaving out att is very common in everyday Swedish when it introduces a subclause containing a statement or opinion.
Why use tycker here instead of tror?
Tycker is used for subjective opinions. By using it here, you are saying you have actually looked at the clue and formed the opinion that it is logical. If you used tror, it would mean you are merely guessing or assuming it is logical without having analyzed it yourself.
Why do we say den första ledtråden instead of just den första ledtråd?
This is a refresher on Swedish "double definiteness." Because there is an adjective (första) describing a specific noun, you must use both the standalone definite article (den) AND the definite suffix on the noun itself (-en in ledtråden).
Why does logisk not end in -a here, since we are talking about a definite noun?
