Question

Use the correct part of speech and complete the passage.

Answer 1

Answer:

A final broad classification which is sometimes used to categorize nouns is the distinction between variable and non variable nouns.

Variable nouns are those which have a singular and a plural form, whereas invariable nouns don't. So count nouns are variable but mass nouns aren't.

However, there are some irregularities dotted throughout the system. A few count nouns, such as sheep and deer, have no actual marker of plurality and a plural sense.
