Learn Turkish: İstasyonda otobüsten in! - Get off the bus at the station!

In Turkish, the verb inmek (to get off, to go down) requires you to use the "from" ending (the ablative case) on the vehicle or place you are leaving. It directly answers the question Nereden? (From where?). So in Turkish, you literally say "get off from the bus" (otobüsten in).

Why is the "from" ending spelled -ten here instead of -den?

This happens because of a pronunciation rule called consonant mutation. The word otobüs ends with a hard, voiceless consonant (s). When you add a suffix that normally starts with d (like -den), the hard s forces the soft d to change into a hard t, making it -ten.

Does istasyonda answer the question Nerede (where) or Nereye (where to)?

It answers Nerede? (Where?). The ending -da means "at", "in", or "on". Even though getting off a bus feels like movement, you are performing the action of getting off at a specific location. Therefore, you use istasyonda (at the station) rather than a "to" ending.

Why is the verb just in without any person or time endings?
