[OT] Next word in this sequence of words ending with 'ty'

[Justin Johansson]

D friends,

Yep, off topic for sure, but this is the best ng that I know of to
get quick answers :-)

May I please have your suggestions for the next English word that
comes semantically/mathematically in sequence.  Ideally the word
ends in "ty" and the semantic sequence is obviously to do with
the predecessor (cardinality-wise) of "Singularity".

Plurality, Singularity, ..

I've got some ideas of my own but do not want to preempt answers.

btw. From my googling of anthropological conceptuality, it appears
that "oneness" and "manyness" are well-understood concepts but
that the concept of "ziltch" is much less featured in lay-society.

Cheers
Justin Johansson
