Questions & Answers about Oletko vihainen?
Why does the sentence start with Oletko instead of a question word?
In Finnish, to ask a yes/no question, you take the word you are asking about, move it to the beginning of the sentence, and attach the question ending -ko or -kö. Here, olet means 'you are', so adding the ending makes oletko, which means 'are you?'.
Why did we use -ko instead of -kö at the end of olet?
This is because of vowel harmony. Suffixes change their vowels to match the main word. The word olet contains the back vowel o (and the neutral vowel e). Because there is a back vowel present, the suffix must also use the back vowel o, making it -ko. If the word only had front vowels like ä, ö, or y, or only neutral vowels, we would use -kö instead.
Where is the word for 'you' in this sentence?
The word for 'you' is built right into the verb! The verb ending -t in olet already means 'you' (singular). You could say Oletko sinä vihainen? by adding the pronoun sinä, but Finnish speakers usually drop it because the verb ending makes it completely clear who you are talking to.
Does the word vihainen change depending on who is angry?
Yes, but since this sentence is about one person, vihainen is in its basic, singular form. If you were asking multiple people ('Are you all angry?'), the adjective would need to change to a plural form. In Finnish, adjectives have to match the number of the people or things they are describing.
