A zero plural marker is a noun that appears singular but is actually a plural.<\/p>\n
Think of a noun, any noun. Because I\u2019m me, I instantly think cat<\/em>, so let\u2019s go with that for a moment. Cat<\/em> is what is referred to as a count noun<\/em>, a noun that can be counted. When there are multiple, the word cat<\/em> becomes cats<\/em>. The \u2018s\u2019 here is called a plural marker<\/em>. When words abide by this rule (or other variations of the rule\u2014think candelabrum<\/em> and candelabra<\/em>, for example), they are regular nouns.<\/p>\n However, when a noun that becomes plural does not include the plural marker, it is called a zero plural marker<\/em> noun. They are irregular nouns and are few in number. Here are some examples:<\/p>\n \n One sheep, two sheep, many sheep<\/p>\n One deer, two deer, many deer<\/p>\n One fish, two fish, many fish\n<\/p><\/blockquote>\n Others include:<\/p>\n \n One aircraft, many aircraft<\/p>\n One offspring, several offspring<\/p>\n A single moose, too many moose<\/p>\n The bison, the herd of bison<\/p>\n One foot, six foot (measurement)<\/p>\n A pound, ten pound (currency)<\/p>\n A stone, three stone (weight)\n<\/p><\/blockquote>\n
