soi'ai PABOI experimental cmavo

almost all/almost every/almost everywhere (technical sense): there is a non-universal conull subset (the complementary (sub)set of which is non-empty but of measure 0, where complement is taken with respect/relative to the universal set) of such things that are satisfactory.

Important point: This word further assumes that the complementary set is non-empty, meaning that this word cannot mean "literally and affirmatively all/every/everywhere" (which is "ro"); this is similar to how "re" is not the same as "su'o re"; in order to include both possibilities, use "su'osoi'ai". Additionally, this word can be used as a quantifier. See also: "soi'au", "pisoi'ai".

In notes:

pisoi'ai (comp!)
almost all of/almost 1/almost surely/almost certainly (technical sense), but not "exactly all of" or "guaranteed" (sense: anti-impossible).
pisu'osoi'ai (comp!)
digit/number: at least almost-all of; at least almost-certain; 100%.
su'osoi'ai (comp!)
digit/number: at least almost-all/at least almost-every/at least almost-everywhere; the complementary set is null and may even be empty.
soi'au (exp!)
almost none/almost no/almost nowhere (technical sense): the subset of satisfactory such things is null but non-empty.
