Questions & Answers about Vad tycker du om teorin?
Why use tycker in this sentence instead of tror or tänker?
We use tycker because the speaker is asking for a personal opinion or impression of the theory. tror is used when asking what someone believes to be factually true (like making a guess), and tänker is used for the literal act of pondering or having thoughts in your head.
Doesn't tycker om mean "like"? Why doesn't this sentence mean "What do you like the theory"?
This is a very common trap! While the phrase tycker om means "to like", in this specific question format, they act as separate words. Vad tycker du means "What is your opinion", and the preposition om just means "about". Together, it translates to "What do you think about...".
Why does the word for theory end in -n here (teorin)?
Because it is in the definite form, meaning "the theory" rather than just "a theory" (en teori). Since the noun teori ends in a vowel, we just add an -n to the end to make it definite.
