Questions & Answers about Moi! Oletko sinä opiskelija?
Why does the verb olet have -ko at the end?
In Finnish, you create a yes/no question by attaching the question particle -ko (or -kö) to the word you are asking about. Since olet means "you are", adding -ko turns it into "are you?".
Do I have to include the word sinä here?
No, it's optional! The verb form olet already tells us that the subject is "you". You could simply ask Oletko opiskelija? and it would mean the exact same thing. Adding sinä just puts a little more focus or emphasis on the person you are talking to.
Where is the word for "a" in "a student"?
Finnish doesn't have articles like "a", "an", or "the". The single word opiskelija automatically translates to "a student" in this sentence. You just add the English article when translating to make it sound natural.
Is Moi appropriate for all situations?
Moi is a casual, friendly greeting, exactly like "hi" in English. You will use it all the time with friends, colleagues, and in everyday places like cafes, but you might want a more formal greeting (like Päivää) in very official or strict situations.
