Internal grammar of quantifiers

quantifier proportional / fractional
fractional [prefix] pi (indefinite / definite / prefix)
proportional simple & simple [fi'u (ro & definite) / ce'i]
simple prefix & (indefinite / definite)
prefix da'a & (su'o / su'e / me'i / za'u / ji'i) & da'a
indefinite so'u / so'o / so'i / so'e / so'a / ro / mo'a / rau / du'e / no'o
definite (no / pa / re / ci / vo / mu / xa / ze / bi / so / ki'o) ...

[ ] indicates the enclosed element is optional ... indicates the preceding element may appear one or more times / indicates either the preceding or the following element may appear & indicates the preceding, the following or both elements may appear

Defaults for bare prefix

When a prefix is not followed by a definite or indefinite, a default value is understood: the default is pa for su'o, su'e, za'u and da'a; ro for me'i; and a vague number (perhaps no'o) for ji'i.

Two adjacent simple quantifiers

  • Two adjacent simple quantifiers are interpreted, when possible, as if joined with .e:
 ro ci broda 
 all three brodas, all brodas and three brodas.
 rau su'o mu broda
 enough at least five brodas, enough brodas and at least five brodas.
 su'o ci su'e bi broda
 at least three at most eight brodas
 at least three brodas and at most eight brodas
 between three and eight brodas (inclusive)
  • Two adjacent simple quantifiers are interpreted, when joining them with .e would give a contradiction, as if joined with .a:
 me'i ci za'u ci broda
 less than three more than three brodas
 less than three brodas or more than three brodas
 i.e. other than three brodas
 mo'a du'e broda
 too few too many brodas
 too few brodas or too many brodas
 the wrong number of brodas


Proportional quantifiers

re fi'u ci broda Two out of every three brodas. Two thirds of brodas.

za'u vo fi'u mu broda More than four out of every five brodas. More than four fifths of brodas.

du'a fi'u ro muno broda Too many out of all 50 broda. Too many broda, of which there are 50 in all.

  • ce'i is equivalent to fi'u panono:
za'u munoce'i broda
More than half of all brodas.
da'a cirepimu ce'i broda
All but 32.5% of brodas.

Fractional quantifiers

piPA sumti lo piPA si'e be sumti

When a sumti has a single referent (which may be a simple individual, a group, a set, etc.) then a fractional quantifier refers to a corresponding fraction of the referent. In particular, a fraction of a group or a set is a subgroup or subset whose cardinality is the corresponding fraction of the cardinality of the whole.

When a sumti has more than one referent (e.g. le ci plise) then a fractional quantifier refers to a fraction of one (which one is not specified) of the referents. Then pimu le ci plise is "half of one of the three apples. Then more generally we can define:

piPA sumti lo piPA si'e be pa me sumti

which will also cover the case of a single referent.

We may then generalize to things like repimu le ci plise for "two and a half of the three apples".
