How to make Plurals?

In general
 
Nouns are most frequently changed from singular to plural form by adding an "s" to the noun (band-bands, team-teams, Asian-Asians).
 Words to watch out for
 
1. Some nouns require the addition of "es" in order to make the plural form. Nouns that end in -ch, -s, -sh, -x, or -z require the addition of "es" (church-churches, box-boxes, wish-wishes).

2. Some nouns that end in "f" or "fe" form the plural by changing the "f" to "v" and adding "-es" (half- halves).

3. Nouns that end in a consonant followed by a "y" change the "y" to "i" and add "es" (country-countries, diary-diaries).

4. Nouns that end in a vowel followed by "y" keep the "y" and just add "s" (array-arrays, play-plays).

5. A few nouns form the plural in an irregular way by changing the spelling of the word (woman-women, man-men, child-children).

6. Some nouns use the same form for both singular and plural meanings (deer, sheep, moose).

7. When a noun ends in a consonant followed by "o," add "es" (echo-echoes).

8. When a noun ends in a vowel followed by "o," add "s" (rodeo-rodeos).

Notice:

We do not use apostrophes to make the plural of most nouns. They are used to make the plural of letters (A?s, abc?s) or words being considered as individual words in the sentence (be careful of your to?s, two?s, and too?s).

Most abstract nouns are not considered in the plural because an idea can?t be counted or given a number value.
