In the theory of computation, a regular language is a type of formal language that can be defined by a regular expression or a deterministic or non-deterministic finite automaton.

One way to identify if a language is regular is to check if it can be described by a regular expression. If a language can be generated by a regular expression, it is a regular language.

Another way is to check if it can be recognized by a finite automaton. If a language can be accepted by a deterministic or non-deterministic finite automaton, it is a regular language.

There are also a number of closure properties of regular languages that can be used to determine if a language is regular. For example, regular languages are closed under union, concatenation, and Kleene star operations. If a language can be expressed as the union, concatenation, or Kleene star of regular languages, then it is also a regular language.
