This is the 211th most frequent Armenian word.
հիվանդության
The Armenian word "հիվանդության" translates to "disease" or "illness" in English.
Here, 'հիվանդության' (of disease) is used in a possessive sense to describe the disease whose recognition is discussed. I would teach students about the possessive relationships and their typical constructions in Armenian.
Այս հիվանդության ճանաչումը շատ կարևոր է վաղ փուլերում։
Recognition of this disease is very important at early stages.
In this context, 'հիվանդության' (illness) appears to indicate the illness related to her family. This example serves to teach the usage of genitive case to introduce topics of discussion or aspects related to a subject.
Նա պատմում էր իր ընտանիքի հիվանդության մասին։
She was talking about her family's illness.
In this sentence, the word 'հիվանդության' (of illness) is used in the genitive case to indicate the cause or reason for an action. As a teacher, I would explain how in Armenian syntax the genitive case often introduces causality or possession.
