Number

In English grammar, Number refers to the distinction between singular and plural forms of nouns, pronouns, and verbs. It indicates whether we are talking about one or more than one person, place, thing, or idea.

Singular Number denotes one entity, while Plural Number signifies more than one.

Rules for Forming Plurals

The reference text outlines various rules and exceptions for creating plural forms of nouns:

1. Regular Plurals:

   • Most nouns form their plurals by simply adding -s to the singular form
     • book -> books, chair -> chairs
   • Nouns ending in -s, -ss, -sh, -ch, -x, or -z add -es
     • class -> classes, bush -> bushes, box -> boxes

2. Nouns ending in -f or -fe:

   • Generally change -f or -fe to -ves
     • calf -> calves, knife -> knives
   • Some nouns simply add -s
     • proof -> proofs, gulf -> gulfs
   • The word ‘dwarf’ has two acceptable plural forms: dwarfs or dwarves

3. Nouns ending in -o:

   • Some nouns ending in -o add -es
     • echo -> echoes, hero -> heroes
   • Others add -s
     • piano -> pianos, photo -> photos

4. Nouns ending in -y:

   • If a consonant precedes the -y, change -y to -ies
     • country -> countries, lady -> ladies
   • If a vowel precedes the -y, add -s
     • day -> days, boy -> boys

5. Irregular Plurals:

   • Some nouns form plurals by changing vowels or using different words
     • woman -> women, man -> men, child -> children

6. Compound Nouns:

   • In most compound nouns, the plural is formed by adding -s to the principal word
     • father-in-law -> fathers-in-law
   • If there’s no noun element, -s is added to the end
     • grown-up -> grown-ups

7. Foreign Plurals:

   • Some nouns retain their original plural forms from other languages
     • curriculum -> curricula, datum -> data

8. Nouns with the same Singular and Plural forms:

   • deer, sheep, fish, series, species

9. Plurals formed using apostrophe + s (‘s)

   • Used for abbreviations, letters, and numerals
     • M.A. -> M.A.’s, 5 -> 5’s

Important Considerations

• Subject-Verb Agreement: The number of the subject (singular or plural) determines the form of the verb used in a sentence.
• Countable and Uncountable Nouns: Countable nouns have both singular and plural forms, while uncountable nouns are typically singular and require specific quantifiers (e.g., a piece of advice, a cup of tea).
• Collective Nouns: Collective nouns can be singular or plural depending on whether they refer to the group as a single unit or its individual members.
