All nouns have plurals. Plurals are when you have more than one of something. For example:
Sweet red ripe apples.
Radios.
Fish. (Two of them.)
Well-dressed cartographers.
Japanese businessmen on vacation in Prague.
Monkees songs.
Those are all plurals, as opposed to singular versions of things, which are when you have just one of something. To wit:
Sweet red ripe apple.
Radio.
Fish. (One of them.)
Plurals can be many things, and they can connote many things. They can be happy:
Well-dressed cartographers who just won an award for mapping the Rio Grande in its entirety.
And they can be sad:
Well-dressed cartographers who just lost their grant funding because of goverment cutbacks.
“Government cutbacks” is also a plural. A very very sad plural.
Plurals can be happier than their singular versions:
Japanese businessmen on vacation in Prague. (Happy)
One depressed, divorced, lonely, and spiritually bankrupt Japanese businessman on vacation in Prague. (Sad)
And singular versions can in turn be happier than their plurals:
A Monkees song on the radio. (Happy)
Several Monkees songs being covered by Smashmouth constantly on the radio, television, and Internet.
I hope you now fully understand the difference between plurals and singular versions of things. It’s a very important thing to know. Up until recently, I don’t think I fully understood the difference myself. But now I do, I really do, I understand it completely. There was one particular plural I was a little unclear on, but with the help of some friends I think I am now 100%, A-Number 1, totally, fully clear on it. And you should be, too. Never forget this next plural/singular series, which I consider to be the most important, but most subtle, of all:
I have a girlfriend. (singular) (Happy)
She went on a vacation to Prague. (singular) (Happy for her, but sad for me, but happy for Prague)
My girlfriend cheated on me. (singular) (Not particularly happy, but not the end of the world)
My girlfriend cheated on me. (plural) (Sad)
My girlfriend blew Phish. (All of them.) (Extremely plural) (Extremely sad)
