Questions & Answers about Muutto tapahtui aiemmin kuin luulin.
Why use luulin instead of ajattelin for "I thought" here?
The verb luulla means to suppose, assume, or believe something, often when that assumption turns out to be wrong. Since the move happened at a different time than expected, luulin is the perfect choice. Ajatella refers to the active, ongoing process of thinking in your head.
Is aiemmin the same as aikaisemmin?
Yes! Aiemmin and aikaisemmin both mean "earlier" and can be used interchangeably in this sentence. They are comparative forms related to time. While this lesson focuses on postpositions like sitten for specific amounts of time (like "a week ago"), aiemmin is used when comparing general points in time.
How do we know muutto means "the move" as a noun, rather than a verb?
Muutto is a noun formed from the verb muuttaa (to move/relocate). Finnish often creates action nouns by taking the verb stem and adding -o or -ö. Because it is a noun, it acts as the subject of the sentence here, performing the verb tapahtui (happened).
Why isn't there an extra word for "what" or "it" after kuin?
In Finnish, the conjunction kuin (than) can connect directly to the verb luulin (I thought) without needing a dummy pronoun or filler word. The structure aiemmin kuin luulin is very direct and closely mirrors the English phrase "earlier than I thought".
