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, Kleene*, and Concatenation.

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 in L2, or in both.

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

4. Concatenation: The concatenation of two languages L1 and L2, denoted as L1.L2 or L1L2, is a language that includes all possible strings that can be made by concatenating a string from L1 with a string from L2.

By applying these operations to the basic languages, we can obtain all possible regular languages over ∑.
