Strings commonly contain a mixture of words and other delimiters. Sometimes, these strings may delimit words by a change in the case without whitespace. For example, the camel case capitalizes each word after the first, and the title case (or Pascal case) capitalizes every word.

Camel case is distinct from several other styles: title case, which capitalizes all words but retains the spaces between them; Tall Man lettering, which uses capitals to emphasize the differences between similar-looking product names such as predniSONE and predniSOLONE; and snake case, which uses underscores interspersed with lowercase letters (sometimes with the first letter capitalized).
