Questions & Answers about Bizim ofisimiz zemin katta değil, birinci katta.
How is the word birinci formed?
bir means "one". To make it "first", we add the ordinal suffix -(I)ncI. Since bir ends in a consonant and its vowel is "i", 4-way vowel harmony makes the suffix -inci, giving us birinci.
Does birinci kat mean the ground floor or the floor above it?
In Turkey, buildings are numbered like they are in Europe, which might surprise American learners. The street level is the zemin kat (ground floor). The birinci kat (first floor) is one flight of stairs up. So, this office is on the floor above the street!
Why use both bizim and the -imiz ending on ofisimiz? Isn't that saying "our" twice?
Yes, ofisimiz alone already means "our office". Adding the pronoun bizim isn't strictly necessary, but it is often used for emphasis. Here, it sounds like the speaker is making a contrast: "Our office is on the first floor (but maybe someone else's is on the ground floor)."
Why is the locative suffix (on/at) spelled -ta in katta instead of -da?
