A regular language over an alphabet is a language that can be recognized by a finite state automaton or a regular expression. It is a set of strings formed by a finite combination of symbols from the alphabet. Regular languages are closed under several operations such as union, intersection, and concatenation, and they are used in many applications such as text processing, compiler design, and natural language processing. Examples of regular languages include the set of all strings of 0s and 1s with an even number of 0s, the set of all strings that start with 'a' and end with 'b', and the set of all strings that contain only the symbols 'a' and 'b'.

A regular language over an alphabet is a language that can be recognized by a deterministic finite automaton (DFA) or a non-deterministic finite automaton (NFA) with a single final state. In other words, it is a language that can be generated by a regular expression or described by a finite state machine. Regular languages are closed under union, concatenation, and Kleene star operations, meaning that the result of applying any of these operations to two regular languages is also a regular language. Common examples of regular languages include the set of all strings consisting of 0's and 1's with an even number of 0's, and the set of all strings of the form "abab" or "abba".
