lowercase

Lowercase letters aren't capitalized — they're the smaller versions of each letter. For example, this is a lowercase "a" while this its big brother: the capital "A." Sometimes people get sloppy and write in all lowercase letters on email.

In English, we capitalize (or use uppercase letters) when we write someone's name, a book's title, or the name of a country. Otherwise, our writing is full of lowercase letters. Every letter in the alphabet has an uppercase and lowercase version, the latter being mainly smaller and shorter on a printed page. In typography, capital letters are all the same height, while the size of lowercase letters varies (think of an a compared with a j, for example).
