ilkelerinin
İlkelerinin is a Turkish bound form that expresses possession and relation to principles. It is derived from ilke, meaning principle or rule, in its plural form ilkeler, and then inflected with suffixes to convey “their” and “of.” In practice, ilkelerinin translates roughly as “of their principles” or, in a broader sense, as “their principles.”
Morphologically, Turkish forms are built by attaching multiple suffixes in sequence. From ilke you get ilkeler
Usage and nuance: ilkelerinin is used in contexts where one discusses the normative framework or ethical codes
Example: Onların ilkelerinin bu süreçte nasıl değiştiğini incelemek önemlidir. Translation: It is important to examine how
