Fly and Flies: Singular and Plural Usage

A common error in English usage is to use singular and not plural. This error reveals the speaker's poor grammar, and English as a second language. For example, you should say, "there is a fly in my soup." Do not say, "there is fly in my soup." That is incorrect and sounds wrong to the trained American and English ear.

Another example would be to say, "there are bugs in my code," and not, "there is bug in my code." Either there is one bug, a bug, or there are two bugs, many bugs.
