A plural noun names more than one person, place or thing. Mastering the rules for plurals takes practice. When do you add an “es” rather than an “s”? How do you know when to change a “y” to an “i”? Another common question is, what is the plural of deer or moose? Or the plural of curriculum or thesis? Syllabus, crisis, bus, criteria, bacteria?
