Latin letters refer to the collection of letters that make up the Latin alphabet, also known as the Roman alphabet. The Latin alphabet was originally used by the ancient Romans to write the Latin language and has since been used to write many modern European languages, including English. The Classical Latin alphabet consisted of 23 letters, 21 of which were derived from the Etruscan alphabet. In medieval times, the letter "I" was differentiated into "I" and "J," and "V" was differentiated into "U," "V," and "W," producing an alphabet equivalent to that of modern English with 26 letters. Many languages supplement the basic Latin alphabet with a variety of accented letters and special characters. The modern Latin alphabet is used to write hundreds of different languages, each of which uses a slightly different set of letters, and they are pronounced in various ways. Some languages use the standard 26 letters, some use fewer, and others use more. The Latin alphabet has had many different forms and has been adapted to write many different languages.
