Questions & Answers about Resimleri duvara düzgünce asmalısın.
The suffix -i is the accusative (definite object) marker. In Turkish, if the direct object is specific or “definite” (like “the pictures” rather than “pictures in general”), you add -i (with vowel and consonant harmony).
• resim + ler (plural) → resimler
• resimler + i (definite object) → resimleri
So Resimleri means “the pictures” as the definite thing you’re hanging.
The suffix -ce (one of -ca, -ce, -ça, -çe, chosen by vowel harmony) turns an adjective into an adverb of manner.
• düzgün (adjective: “neat, proper”)
• düzgün + -ce → düzgünce (“neatly,” “in a neat manner”)
asmalısın breaks down as:
• asmak = “to hang”
• -malı/-meli = necessity/obligation suffix (“must,” “have to”)
• -sın = 2nd person singular ending (“you”)
By vowel harmony, -malı attaches (since “a” in as-). So as + -malı + -sın = asmalısın → “you must/you should hang.”
The default Turkish word order is Subject–Object–Indirect Object/Adverbial–Verb (S-O-IO/Adv-V). In our sentence:
(You) – Resimleri (O) – duvara (IO/place) – düzgünce (adverb) – asmalısın (V).
Turkish is relatively flexible, but the verb typically comes last.
