* If "élève" refers to a male student, the definite article is "le": Le élève
* If "élève" refers to a female student, the definite article is "la": La élève
However, it's important to note that "élève" is a noun that is almost always used in the plural form. In the plural, the definite article is always "les": Les élèves.
Therefore, it's rarely necessary to use the singular form of "élève" with a definite article.
