x_{1} (set) is measurable and has measure x_{2} (li; non-negative real number or possibly positive infinity) by measure x_{3} in space/dimensionality/under conditions x_{4}; x_{2} is the x_{3} measure of set x_{1} in space x_{4}; x_{3} is a measure which is defined on some class of measurable sets in
x_{4} such that it maps x_{1} to x_{2}

A type of klenilbra (notice rearranged terbri). "Measure-0 set" = "set of measure 0" = "lo umre be li no". 0 is indeed a measure (value). In general, this dictionary definition does not require that there exists at least one measurable set that gets mapped by x_{3} to a finite (x_{2}) value; that condition may be imposed by context.

- zi'au
*(exp!)* - nonexistent/undefining it; the selbri is not applicable when the other terbri are filled in the manner in which they are in this utterance/bridi.
