Base NounThe singular form of a noun, to which a suffix is added to form the plural.In the word 'shelves', the base noun is 'shelf'.

Key Rules & Conventions
The -f and -fe Rule
For most nouns ending in -f or -fe, change the f or fe to v and add -es.
This is a common phonetic shift in English. However, there are many significant exceptions (like 'roofs' and 'chiefs') that must be memorized, as they often relate to the word's origin and historical usage.
The -y Rule
If a noun ends in a consonant + y, change the y to i and add -es. If a noun ends in a vowel + y, simply add -s.
The key is to identify the letter immediately preceding the final 'y'. This rule is highly consistent with very few exceptions, making it one of the more reliable pluralization patterns.
The -o Rule
If a noun ends in a consonant + o, usually add -es. If a noun ends in a vowel + o, add -s.
This rule is riddled with ex...

Challenging
Evaluate the plural nouns in the following sentence from a research methodology paper: 'The two research assistants compiled portfolios of data, including photos of the stratovolcanoes and memos on their daily activities.' Which statement is accurate?
A.All plural nouns in the sentence are correct.
B.'Portfolios' and 'photos' are correct, but 'stratovolcanoes' and 'memos' are incorrect.
C.'Stratovolcanoes' is incorrect; it should be 'stratovolcanos'.
D.'Memos' is incorrect; it should be 'memoes'.
Challenging
Which statement best articulates the morphological principle behind the two different rules for pluralizing nouns ending in -y?
A.Nouns ending in vowel + y are typically older English words, while nouns ending in consonant + y are from French, requiring a different suffix.
B.The 'vowel-consonant pattern' dictates the rule; changing y to i after a consonant creates a more phonetically stable ending ('-ies') than adding an s directly.
C.The rule is arbitrary and exists only to create a distinction between different classes of words for the sake of complexity.
D.Changing y to i only occurs when the noun is also a verb, to avoid confusion between forms like 'studies' (noun) and 'studies' (verb).
