Converts a sumti into a tanru-unit with place structure "x1 is/are among the referents of the sumti".
me'u (MEhU)
Terminator for ME.
moi (MOI)
Converts a number, lerfu-string or ME-converted sumti into a tanru-unit. The place structure in the case of a number is "x1 is/are the numberth among x2 by rule x3". More generally, for any sumti the place structure is "x1 is/are the one(s) among x2 that correspond(s) to number/lerfu/sumti by rule x3".
mei (MOI)
Converts a number, lerfu-string or ME-converted sumti into a tanru-unit. The place structure in the case of a number is "x1 are number in number among x2". In general for any sumti the place structure is "x1 is/are among x2, quantified by number/lerfu/sumti".
si'e (MOI)
Converts a number, lerfu-string or ME-converted sumti into a tanru-unit with place structure "x1 is a part/fraction of x2, quantified by number/lerfu/sumti".
cu'o (MOI)
Converts a number, lerfu-string or ME-converted sumti into a tanru-unit with place structure "x1 has an expectation/probability number/lerfu/sumti under conditions x2".
va'e (MOI)
Converts a number, lerfu-string or ME-converted sumti into a tanru-unit with place structure "x1 has value number/lerfu/sumti on scale x3".

Notes
The definition of me corresponds to the basic relation Among as formalized in http://philosophy.syr.edu/mckay.html, which also agrees with the definition as given in CLL.
The interpretation proposed for a ME-converted sumti with moi is an extension of the definition for n-moi as n-th.
The second argument of mei is changed with respect to CLL, to make it more useful and more in line with the rest of the system.
