The Greek alphabet is a set of twenty-four letters that has been used to write the Greek language since the late 19th or early 18th century BCE. It is the first and oldest alphabet in the narrow sense that it notes each vowel and consonant with a separate symbol. It is as such in continuous use to this day. The letters were also used to represent Greek numerals, beginning in the 2nd century BCE. F is the twenty first (21) letter of the Greek alphabet.
