üzerlerinde
Üzerlerinde is a Turkish word that functions as a postposition and is the plural form of the postposition "üzerinde". It translates to "on them," "upon them," or "above them" in English, depending on the context. It indicates a location or position relative to multiple preceding entities. For instance, in the sentence "Kitaplar masanın üzerlerinde duruyor" (The books are standing on them, the tables), "masanın üzerlerinde" refers to the tops of the tables. Similarly, "Çocukların üzerlerinde kırmızı şapkalar vardı" (The children had red hats on them) uses "üzerlerinde" to denote the hats being worn on their bodies. The word is formed by the noun "yüz" (face, surface) which evolved into "üst" (top, upper part), then "üzeri" (its top), and finally "üzerinde" (on it). The plural suffix "-ler" is added, followed by the possessive suffix "-i" which is then changed to the locative case "-de" in Turkish grammar, becoming "üzerlerinde". This postposition is commonly used in everyday Turkish to specify the location of something in relation to multiple objects or beings.
