Questions & Answers about En ole vielä käynyt virastossa.
Why does this sentence use ole instead of olen?
This is the perfect tense in the negative. While "I have visited" is olen käynyt, the negative drops the personal ending from the auxiliary verb. You use the negative verb en plus the base form ole, followed by the past participle käynyt.
How do we form käynyt from the basic verb käydä (to visit)?
Käydä is a Type 2 verb. To form the past participle (the part used after olla in the perfect tense), you remove the -dä ending and add -nyt. Since the word has front vowels (ä, y), vowel harmony dictates we use -nyt instead of -nut.
Why is the ending -ssa (in) used for virastossa instead of a direction ending like "into"?
Does vielä always go in the middle of the verb structure?
Placing vielä between the auxiliary part (en ole) and the main verb (käynyt) is the most natural word order here. However, you could also put it at the very end of the sentence: En ole käynyt virastossa vielä.
