"Αυτός πηγαίνει στον καθηγητή."

Translation: He is going to the professor.

[HastaLaVista83]

It seems that in Greece the preposition "σε" is kind of a universal preposition since it can be used in so many situations. In other languages I know like Russian, Italian and especially German, you have so many different prepositions and you cannot just use the same for different situations.

[LauraBlume]

Yes - it means in, on, at, and to.

[carmina_banana]

Does it have an... "agressive" meaning? (Maybe depending on the context...)

[GiannisMil4]

No it just means that he is heading to the teacher without any aggresive meaning

[Nikos48739]

It also translates to 'going' which is the gerund I guess.

[jaye16]

No, this isn't gerund it's present continuous tense.

[LauraBlume]

"He is going to the instructor" should be accepted.

[jaye16]

Thank you "instructor" has been added.

[LadyMac1000]

This isn't a gerund form and is confusing to be included in this skill set.

[jaye16]

You're right and the "Gerund Skill" was one of the fist to be removed when we started to create the new tree.
