Collective Nouns

Collective Nouns
Nouns are simply the names we give to everything around us, whether it be a person, an event, a place or an object, etc. Every particular name used to define something is a noun. E.g. : Amsterdam, Anita, Blackberry, Honesty, Waiter, etc.
The names given to a group of noun to identify them as a whole are calledCollective Nouns. E.g.: pride of lions, gaggle of geese etc.
Nouns or pronouns can also modify themselves to show possession of another noun, usually by attaching ‘s’ to the end of the noun. These nouns that show possession are called Possessive Nouns.

Sometimes nouns have different forms for different genders, although this practice has been largely abandoned by the people who prefer to use the same noun for both genders. For example – Actor (male) – Actress (female), but people nowadays refer to women who act as female actors rather than actresses.
Most nouns can be converted into plural forms by adding ‘-s’ or ‘-es’ at the end of the word. E.g.: box-boxes, cat-cats, echo-echoes , etc.
But some nouns require the last consonant to be modified before adding ‘-es’. For e.g.: the ‘Y’ in ‘city’ changes to ‘I’ to form cities, kitty to kitties and ‘f’ to ‘v’ in dwarf to dwarves, wharf to wharves, etc.
Some nouns become plurals irregularly by changing the entire word: mouse- mice, ox – oxen, etc.
