Convert text to lowercase

Convert text to all lowercase letters. Here is an example. The word HELLO becomes hello.

In contrast to uppercase or capital letters, lowercase letters appear in certain language such as those that use the Latin or Cyrillic alphabets. As an example the letters a, b, and c are in lower case while the letters A, B, and C are in upper case. Some writing systems make no distinction between uppercase and lowercase letters and are called unicase. With an uppercase and lowercase letter normally the sound the letter represents is the same. Another alphabet that uses upper and lower case is Cyrillic.

Some languages have only lower case letters, but normally if a letter has an uppercase, the letter has a corresponding lowercase. Grammar rules and conventions normally determine when to use uppercase and lowercase. For some acronyms such as HTML, you sometimes see html, but this is not normally considered standard usage and should appear in upper case. Explanations of use of upper case and lower case appear in grammar books and style guides such as with AP style or a reference such as the Chicago Manual of Style. Lowercase is also not used for the first letter in a proper noun.
