Here's a handout on nouns which I give my students to help them understand irregular plural noun forms.
In English, nouns are divided between the singular and plural form. To make a noun plural, an 's' is usually added to the singular but there are several exceptions to the rule.
Exception 1:
Nouns that in ch, s, sh, x, or z form the plural by adding 'es' to the singular. It's because these words which end in ch, s, sh, x or z would be difficult to pronounce if only an 's' were added. Here are some examples:
branch branches
fox foxes
bus buses
Exception 2:
Nouns that end in 'y' which are preceded by a consonant form the plural by changing the 'y' to 'i' and then adding an 'es'. Here's an example:
city cities
Exception 3:
Nouns that end in 'f' form the plural by changing the 'f' to 'v' and then adding an 'es'. Here are some examples:
half halves
leaf leaves
thief thieves
wolf wolves
Exception 4:
Nouns that end in fe form the plural by changing the f to v and then adding only an 's'. Here are some examples:
knife knives
life lives
Finally, there are many irregular plural noun forms which one must commit to memory. Here are some examples:
man men
woman women
child children
tooth tooth
foot feet
louse lice
mouse mice
ox oxen
goose geese

It's certainly helpful.Thanks.
I'm Confused with the plural form of tooth.... Is it not teeth? thanks....some information here useful to me anyway.
do you know the plural form for "memory"?
The plural form of memory is memories.
The rule is that you change that when you have a Y at the end you change the letter Y to I and then add the letters ES.
If the letter -Y comes after a consonant, then you make the plural with -IES. If it comes after a vowel, you simply add -S; trays, plays, etc.
