In formal languages, an **alphabet** is a finite set of symbols or characters used to construct strings and words. Each symbol in an alphabet is referred to as a "letter." For example: - The binary alphabet consists of two symbols: \{0, 1\}. - The alphabet for the English language can consist of 26 letters: \{A, B, C, ..., Z\}.
