Jonathan taught this session, presenting an introduction to nouns and the endings that they take. This was the fourth session of the course, and it was aimed at covering the material in Lesson III of the book.
Making Plurals in English
In English, our nouns are normally very simple. To form plurals, we just add –s, or –es if the last sound calls for it. Thus, computer simply becomes computers; desk becomes desks; friend becomes friends; and, box (ending in an s sound) becomes boxes. There is a list that all school children must memorize of “irregular” nouns like ox (oxen) and child (children), as well as some that do not change form for the plural (fish can be either one fish or twenty fish).
