egészük

"egészük" is a Hungarian possessive suffix. It is used to indicate possession by a third-person plural subject, meaning "their" or "all of them." The suffix itself is "-ük". For example, "házuk" means "their house." It attaches to a noun to show that the noun belongs to a group of people or things.

The suffix "-ük" is a variant of the possessive suffix "-uk". The choice between "-ük" and "-uk" depends on the vowel harmony rules of Hungarian. If the preceding vowel in the noun stem is a back vowel (a, á, o, ó, u, ú), then "-uk" is used. If the preceding vowel is a front vowel (e, é, i, í, ö, ő, ü, ű), then "-ük" is used. For instance, "könyvük" (their book) uses "-ük" because of the front vowel "ö," while "asztaluk" (their table) uses "-uk" because of the back vowel "a."

This suffix is crucial for demonstrating ownership or association in the Hungarian language when referring to multiple possessors. It is a fundamental part of Hungarian grammar, allowing for precise expression of relationships between nouns and their owners. The grammatical concept of possessive suffixes is common in many languages, but the specific form and rules of Hungarian, like the vowel harmony affecting "-ük" and "-uk," are unique to the language.
