Countable plural
From Teflpedia
A countable plural is a plural (i.e. it has grammatical number of 2 or more) that is a countable noun (so grammatical number is differentiated).
In English, the vast majority of plurals are countable plurals; only a few are uncountable plurals. For example "egg" is a countable plural in "1 egg, 2 eggs, 3 eggs."
