The statement is incorrect. A regular language over an alphabet ∑ is one that can be obtained from the basic languages using the operations of Union, Concatenation, and Kleene*. These operations are fundamental in defining regular languages.

Here's a step-by-step explanation:

1. Basic Languages: These are the simplest form of languages over an alphabet ∑. They consist of all strings of length 1 over ∑, the empty string, and the empty language.

2. Union: The union of two languages L1 and L2, denoted as L1 ∪ L2, is a language that includes all the strings that are in L1 or L2 or both.

3. Concatenation: The concatenation of two languages L1 and L2, denoted as L1.L2 or L1L2, is a language that includes all the strings that can be obtained by taking any string from L1 and any string from L2 and concatenating them.

4. Kleene*: The Kleene star of a language L, denoted as L*, is a language that includes all the strings that can be obtained by concatenating zero or more strings from L.

A regular language is defined as a language that can be obtained by starting with the basic languages and applying the operations of union, concatenation, and Kleene star a finite number of times.
