türündeki
türündeki is a Turkish word that translates to "of its kind," "of its type," or "belonging to its category" in English. It is a possessive suffix attached to a noun to indicate that something is characteristic of or belongs to that specific kind or type. The suffix "-ündeki" is a variation of the possessive suffix "-deki" which itself is a combination of the locative suffix "-de" (meaning "in" or "at") and the demonstrative pronoun "ki" (meaning "that which is"). The vowel harmony rules of Turkish dictate whether "-deki" or "-ündeki" is used, depending on the preceding vowel.
For example, "kuş türündeki hayvanlar" would mean "animals of the bird kind" or "animals that are birds."
