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".
