Plurality of Nouns: The Rules
The rules for making nouns plural are complex and have many exceptions. Here's a breakdown of the most common rules:
1. Regular Plurals:
* Add -s: This is the most common way to form plurals. For example: cat - cats, book - books, table - tables.
* Add -es: Add -es to nouns ending in -s, -x, -ch, -sh, and -z. For example: bus - buses, box - boxes, church - churches, bush - bushes, buzz - buzzes.
* Change -y to -ies: Change -y to -ies for nouns ending in -y preceded by a consonant. For example: baby - babies, city - cities, story - stories.
2. Irregular Plurals:
* Special Forms: Some nouns have irregular plurals that don't follow any set rules. You just have to memorize them. For example: child - children, man - men, tooth - teeth, mouse - mice.
* Same Form: Some nouns have the same form for singular and plural. For example: sheep, deer, fish, series, species.
* No Plural Form: Some nouns are only used in singular form. For example: advice, information, furniture, hair.
3. Compound Nouns:
* Pluralize the Main Noun: For compound nouns, usually the main noun is pluralized. For example: toothbrush - toothbrushes, bookcase - bookcases.
* Pluralize both Nouns: For some compound nouns, both parts are pluralized. For example: passerby - passersby, attorney general - attorneys general.
4. Foreign Nouns:
* Follow Original Rules: Some foreign nouns retain their original plural forms. For example: alumnus - alumni, criterion - criteria, datum - data.
* Adapt to English: Others have adapted to English plural rules. For example: octopus - octopuses/octopodes.
5. Special Cases:
* Numbers and Letters: Numbers and letters are pluralized by adding -s. For example: two - twos, A - As.
* Proper Nouns: Proper nouns (names of people, places, etc.) follow the same rules as regular nouns. For example: Jones - Joneses, London - Londons.
Remember:
* These are just general guidelines. There are many exceptions and variations to these rules.
* It's always best to consult a dictionary for any specific doubts.
* Context can also help determine the correct plural form. For example, "The fish are swimming" is correct, while "The fish is swimming" could refer to a specific type of fish.
Practice makes perfect! The more you read and use English, the more familiar you'll become with the nuances of plural nouns.
