At the matter of fact, if we are asked what is antonym, how can we reply that asking?

Certainly being, being present, that answer could be expected, to some credible regard, nevertheless, some indigested impression could be left to us.
What make me think so is derived from that being and not being is just one mentioning and just denial to it for the present, that impression could never be wiped out from that answering.

For the first time, being's modus ponens is so ambiguous, because it necessarily could not be so specified substance, but that could be some extent, also so nominal identified somewhat otherwise just form e.g. described with relativity toward 0, or so.

To be frank, being is could be both substance and nominal. Because it could be used for substantial modus ponens with relativity toward nothing and presence. Necessarily "presence" could be either so ambivalent.'(but that question should be dealt at another opportunity.)
But simultaneously, it could be used for very abstract usage at regarding all presence in conceptual comprehension.

Nevertheless, more that "nothing", it'd be so clearized at taking substantial context, certainly either nothing could be used for substantial subjective context with usage of being in relativity. But only "nothing" could be used also for both just never substantial it, because it is just none, so "substantially".

Consequently, these usage's interpretation must be relevant with usage context's circumstance. But "being" is not only concept but also so substantial totalized description, but simultaneously it'd be completely extreme larger extent and that is too larger to define so clearly, we could say either so.

However, to my idea, "being" is rather very formally and nominally used, because it is not so concretely mentioned, never yet very abstractly done to us.
Though, how about define it just CONTEXTUAL NOTION.

The last that definition is "substantially" so seemed to be appropriate at least to my own impression. Because that term's extent at usage is too larger to focus so precisely.

Memorandum; Next analysis, we should advance to analysis in relevance with "Presence", "Existence" and "Identity".
