seviyesinden
Seviyesinden is a Turkish grammatical form derived from the noun seviye, meaning level. It is built by adding the possessive suffix -si to form seviyesi (its level) and then the ablative suffix -nden to express origin or starting point, yielding seviyesinden, literally “from its level” or “from the level of.”
In Turkish, seviyesinden is used to indicate origin from a specific level in both literal and figurative
Examples illustrate its use: Köprü, gölün seviyesinden bir metre yükseğe inşa edildi means “The bridge was built
