But if I do it usually, regularly, frequently... you know, isn't it jeżdzić? Why dojeżdzić?
Well I ain't the language teacher.
If you do it regularly it should be dojeżdżać
to work, school and so on..... people would say often jeździć
as well in the case but that is not correct usage.
Obviously i'm wrong because i would've said ' Jade na uniwersytet w pociągu '
Can anyone tell me why this is wrong?
Jadę na uniwersytet pociągiem ? - that present continuous. That is correct provided you are talking on your mobile and telling somebody say your sweetheart your whereabouts.
On the other hand you would have been understood if you would say - Jeżdżę na uniwersytet pociągiem.
