English 101: Singular & Plural Nouns (series 1.A2)

     This is my third in a series of my English 101 on this blog. I am through discussing the different types and kinds of nouns, we will go on how is it when a single noun becomes many.

When we talked about the Number of Nouns, we are referring to Singular and Plural Nouns. Determining the numbers of a noun is vital in sentence construction. Most singular nouns are made plural by only adding "s" to their word. However, there are singular nouns which does not need any changes at all, and some are governed by rules or need changes for most of the letters in a word.

Here are some words which stay the same in plural form:

words with a suffix of -craft, 
sheep, cod, swine, trout, deer, salmon, moose, series, species, Japanese, Chinese, fish (fishes can be used if referring to different species)

Here are the lists of rules for changing singular nouns to plural forms.

1) If the noun ends in  's', 'x', 'sh', or 'ch', we add -es to make it plural.
    Examples: bus-buses, box-boxes, bush-bushes, batch-batches,
 
2) If the noun ends in 'o' with a consonant before it, we add -es,
    Examples: mango-mangoes, potatoes

    If a noun ends in 'o' with a vowel before it, we add -s.
    Examples: igloo-igloos, stereo-stereos

3) If the noun ends with 'f' or 'fe', we sometimes change the f or fe to -v and add -es.
    Examples: leaf-leaves, beef-beeves, life-lives, knife-knives

4) If the noun ends in 'y' with a consonant before it, change the y to -i and add -es.
    Examples: battery- batteries, candy-candies, berry-berries, lady-ladies

5) If the noun ends in 'y' with a vowel before it, we add -s to make it plural.
    Examples: monkey-monkeys, journey-journeys, key-keys, decoy-decoys

And here are the lists of some singular nouns that must change their spelling:
child-children, man-men, woman-women, ox-oxen, mouse-mice, foot-feet, tooth-teeth, goose-geese, louse-lice
