The author's previous paper in 'Magyar Nyelvor' discussed some errors, peculiarities, and curiosities of grammatical agreement governed by collective nouns. In the present paper, written with similar methods and aims, he turns to some particulars of the general issue of agreement that share 'quantity' as a common feature. The analysis is based on a data set collected between 1992 and 2003. First, agreement within the quantifier phrase, then (in the lengthiest part of the paper) agreement governed by a quantified noun, and finally, that governed by a quantifier (a numeral used as a noun or a pronoun referring to quantity) is considered.
