​What do you notice?

Why do we capitalize certain words?
How does capitalization help you read?
What rules do you remember about capitalization?

Originally, in most ancient languages, words were written in either all upper-case letters or all lower-case letters to make the words easier to read. As the quality of paper improved, more differentiation was possible. In some languages between “ancient” and today, the most important words in a sentence might be capitalized while the lesser words would not.

Did you know where the terms upper- and lower-case came from?

When a typesetter was at his table preparing the letters for his printing press, the capital letters were kept in the “upper case” of his letter cabinet, while the smaller letters were kept in the “lower case.” See right for pictures!

So, as we saw in this first example, capitalization is important. And, there are a few pretty simple rules to learn and follow. In this unit, we are going to address these rules. You will probably know some of the rules already, while others may be new. But, once you learn the rules, there’s no looking back! You will then be accountable.
