Questions & Answers about Bu tezgahtaki nadir eşyalar çok pahalı.
How is tezgahtaki formed, and why does it use -ta instead of -da?
It is built from the noun tezgah (stall), the locative suffix -ta (on/at), and the adjective-forming suffix -ki (which is). It uses -ta because tezgah ends in 'h', which is an unvoiced consonant (often remembered by the "Fıstıkçı Şahap" rule). This hardens the 'd' in the standard -da suffix into a 't'. Together, tezgahtaki acts as an adjective meaning "that is on the stall".
Does the suffix -ki follow vowel harmony here?
No, it doesn't. The suffix -ki is one of the few exceptions in Turkish that ignores vowel harmony. Even though tezgahta only has back vowels ('a'), the suffix remains -ki instead of changing to -kı.
Why do we say 'Bu tezgahtaki nadir eşyalar' instead of putting 'nadir' first?
In Turkish word order, demonstrative words (like bu) and location adjectives (like tezgahtaki) almost always come before descriptive adjectives (like nadir, meaning "rare"). The phrase flows from the specific location to the description: [This] [on-the-stall] [rare] [items].
Since eşyalar is plural, why don't we say pahalılar at the end of the sentence?
