Questions & Answers about O merdivenden hızlıca iniyor.
The ending -den/-dan/-ten/-tan is the ablative case, meaning “from/off/out of.” With the verb inmek (to descend, go down, get off), Turkish marks the thing you go down or get off with the ablative: you “descend from” it.
- merdiven-den inmek = go down from the stairs
- arabadan inmek = get out of the car
- otobüsten inmek = get off the bus
Form of the suffix changes by vowel harmony and voicing:
- Last vowel front (e, i, ö, ü) → use -den/-ten; back (a, ı, o, u) → -dan/-tan
- After a voiceless consonant (p, ç, t, k, f, h, s, ş), D becomes T: ağaçtan, köprüden, otobüsten
Turkish often uses the singular as a collective for facilities or surfaces, so merdivenden naturally means “(down) the stairs.” Plural merdivenlerden is also possible and emphasizes the multiple steps/staircases, but there’s no difference in basic meaning:
- O merdivenden iniyor. = He/She is going down the stairs.
- O merdivenlerden iniyor. = He/She is going down the stairs. (equally fine)
