almost all of/almost 1/almost surely/almost certainly (technical sense), but not "exactly all of" or "guaranteed" (sense: anti-impossible).
Has/of the full measure but is not literally all of the relevant superset (this word is distinct from and does not include the possibility of "piro"); the complementary subset is null but non-empty. In the context of probability, the result is not absolutely and perfectly certain in theory; alternative outcomes are technically possible. See also: "soi'ai", pisu'osoi'ai".
