Questions & Answers about Oletko sinä ylittänyt valtameren?
Why does the sentence use a form of olla (to be) when the English translation says 'Have you'?
Finnish doesn't have a direct equivalent to the verb 'to have.' Instead, the Finnish perfect tense is formed using the verb olla as the helper verb. Literally, this sentence is constructed as 'Are you crossed the ocean?'.
How is the yes/no question formed in the perfect tense here?
In a perfect tense question, you attach the question particle -ko to the helper verb, not the main verb. Here, olet (you are) gets the -ko ending and moves to the front of the sentence to become Oletko (Have you...?).
What is the base form of ylittänyt, and why does it end in -nyt?
The base verb is ylittää (to cross). In the perfect tense, the main verb takes the past participle form, which ends in -nut or -nyt for singular subjects. Because ylittää contains the front vowels y and ä, vowel harmony requires the -nyt ending.
Why is 'the ocean' written as valtameren instead of the basic form valtameri?
