The Vowel-Change Rule
Some singular nouns change their middle vowels to become plural.

The No-Change Rule
Some nouns are the same whether they are singular or plural.
This rule is common for some types of animals. You use the same word for one of them as you do for a whole group. Examples include 'sheep', 'deer', and 'fish'.
