This document provides a lesson on forming plural nouns in English. It explains that plural nouns name more than one person, place or thing, and that most singular nouns become plural by adding an 's'. For nouns ending in 'sh', 'ch', 'x', 'z', and 's', an 'es' is added instead to form the plural. It then lists 16 singular nouns and asks the student to write the plural form of each.
