Generally variables are named in the singular Car car; and arrays and list with the pluras: List<Car> cars; or Car[] cars; But what about nouns like fish or media* that are already plural?

*already lost the battle to have the class called Medium.

"fishes" is an acceptable plural form of of "fish", at least. –  Izkata Jan 21 at 2:52
    
I often use carList / carArray –  Bryan Chen Jan 22 at 3:13

There are a couple of ways to tackle this problem. None of them are perfect, but you can find a workable solution. The key is that your team needs to come up with a standard approach to resolving this and to stick with it.

Here are some of the options:

  • Different capitalization

The singularly named variable will start with one case (lower case) while the plural variable will start with the other case (upper case).

 var Fish = new List<fish>();  //plural  
 var fish = Fish[0];           //singular
  • Deliberate use of improper grammar

Example:

 var Fishes = new List<fish>();  //plural  
 var fish = Fishes[0];           //singular  

or

 var Meese = new List<Moose>();  //plural  
 var Moose = Meese[0];           //singular
  • Use group name instead

Example:

 var SchoolOfFish = new List<Fish>();  //plural  
 var Fish = SchoolOfFish[0];           //singular

I think names like List<Fish> fish are perfectly fine. We use "fish" as both singular an plural in writing; why not do the same in code?

If you want a singular Fish fish in the same scope, say for iterating, can always switch to List<Fish> fishList or List<Fish> listOfFish.

List<Fish> school –  Adrian Schneider Jan 21 at 3:10
    
mostly because often you haves code conventions like for( Book book : books ) so the singular is already taken or going to be used for something else. –  ArtB Jan 21 at 14:44

My suggestion would be to try to use a more meaningful name for the list variables. I know this is sometimes hard to do, though.

For example, instead of List<Car> cars, use something like List<Car> parkedCars. Instead of Fish[] fish, use something like Fish[] availableFish.
