átmérjének
The Hungarian word "átmérőjének" translates to "its diameter" in English. It is the possessive form of the noun "átmérő," meaning "diameter." The suffix "-jének" indicates the third-person singular possessive and the genitive case. This grammatical structure is used when referring to the diameter belonging to a singular, non-human entity, or an abstract concept. For example, in a sentence like "A kör átmérőjének hossza tíz centiméter," the meaning is "The length of the circle's diameter is ten centimeters." Here, "kör" is circle, and "átmérőjének" signifies that the diameter belongs to the circle. The word is commonly encountered in mathematical, scientific, and technical contexts where measurements and dimensions are discussed. Its usage highlights the grammatical rules of Hungarian regarding possession and case marking.
