ülkelerinin

"ülkelerinin" is a Turkish word. It is the genitive plural form of the word "ülke", which means "country" or "nation". Therefore, "ülkelerinin" translates to "of their countries" or "of the countries".

This word would be used in sentences where possession or belonging to multiple countries is being indicated. For example, in a sentence discussing the economic policies of various nations, one might say "Bu politikalar ülkelerinin kalkınmasına yardımcı oldu," meaning "These policies helped the development of their countries." Similarly, when referring to shared cultural heritage across different nations, the phrase might appear as "Bu miras, ülkelerinin tarihinde önemli bir yer tutar," meaning "This heritage holds an important place in the history of their countries."

The grammatical function of "ülkelerinin" is to show that something belongs to or is associated with more than one country. The "-lerinin" suffix is a common possessive suffix in Turkish, indicating "their" or "of them," and when attached to the plural genitive of "ülke," it forms the specific phrase in question. Understanding this word requires knowledge of Turkish grammar, specifically noun declension and possessive suffixes.
