pisoi'au PA* cmavo-compound

almost none of/almost 0/almost never/almost certainly not/nearly nothing of (technical sense) but technically being non-empty or possible in theory (not impossible).

Having zero measure (not "no measure", since the measure does exist). This word does not contain "pino" in its potential reference; use "pisu'esoi'au" for that. In the context of probability theory, the relevant event is possible, just with probability 0. The relevant set is null but non-empty. See also: "soi'au".

In notes:

pino (comp!)
Number/digit: exactly none of (empty set as a subset of another set); in probability theory, "guaranteed impossible".
pisu'esoi'au (comp!)
digit/number: at most almost-none of (0%, taken as a fraction of a whole); the referent 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.
