Unlike regular English nouns that form the plural by adding 's' or 'es' to the end of the word, irregular English nouns require vowel or consonant changes, or suffixation. For some common nouns of Old English origin, the vowel undergoes a change (ablaut). For example:
- foot > feet
- man > men
- woman > women
- mouse > mice
- tooth > teeth
Some other common nouns of Old English origin require the addition of 'n' or 'en' to form the plural. For example:
- child > children
- ox > oxen
Yet other common nouns, which are often of Old English origin and refer to groups of animals, have identical plural and singular form. For example:
- deer > deer
- moose > moose
- trout > trout
- offspring > offspring
- sheep > sheep

- axis > axes
