Plural
PLU'RAL, adjective [Latin pluralis, from plus, pluris, more.]
1. Containing more than one; consisting of two or more, or designating two or more; as a plural word.
2. In grammar, the plural number is that which designates more than one, that is, any number except one. Thus in most languages, a word in the plural number expresses two or more. But the Greek has a dual number to express two; and the plural expresses more than two.
