existentiality

is the state of being that is constitutive for those entities that exist (but the idea of such a constitutive state of being already includes being as its core component).

The word existentiality is derived from existential, i.e., the formal understanding of Being in general . By 'existentiality' we understand the state of Being that is constitutive for those entities that exist. But the idea of such a constitutive state of Being already includes Being as its core component. And this is the reason why we are prevented in working out the general answer to the question, 'What is Being'' before the question itself has been answered. [ref. 4, page 33] (Mundey)
