This is the 72nd most frequent Slovenian word.
te
"You" (second person singular accusative or dative).
Here, 'te' is the second person singular pronoun in the accusative case.
Včeraj sem te videl na trgu.
Yesterday, I saw you at the square.
In this sentence, 'te' is part of the phrase 'te dni', which means 'these days'.
Te dni je vreme zelo lepo.
These days, the weather is very nice.
Again, 'te' is the second person singular pronoun in the accusative case, referring to the person being called.
