sentences:  Lindström introduced polyadic ones that are "n" > 0-ary relations between relations on domains of structures.Before we go on to Lindström's generalization, notice that any family of properties on dom("A") can be regarded as a monadic generalized quantifier.For example, the quantifier "there are exactly "n" things such that..." is a family of subsets of the domain of a structure, each of which has a cardinality of size "n".
