Capitals

When we type a capital letter at the beginning of a word we are giving that word emphasis, indicating that it is important.

For example, we call attention to the beginning of each sentence with a capitalized word. And we capitalize proper nouns such as Rob to make sure our readers do not mistake them for an unfortunate word such as rob.

The bad news: consensus is often lacking about rules for capitalization. Use a respected reference book and hope for the best.

The good news: concensus is strong about not overusing capitals. When too many words are emphasized, too few stand out.

Class and Instance

We capitalize proper nouns because they name particular things. We do not capitalize common nouns; they identify generic things.

Another way to think of it is this: a common noun names a generic class of things, such as lake, while a proper noun names a particular instance of a lake, such as Lake Titicaca.
