A base and a Lewis base are the same thing. Lewis base just states how Lewis describes bases (donating an electron).

In chemistry, a base is a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution. Types of bases include Arrhenius base, Bronsted-Lowry base, and Lewis base.

There are two definitions for both acids and bases. These are Bronsted acid and bases and Lewis acid and bases, both of which define an acid and a base in a different way. A Bronsted acid is a substance that donates hydrogen ions to the solution it is found in, whereas a Bronsted base is a substance that donates hydroxide ions to the solution it is found in. A lewis acid, on the other hand, is the lone pair acceptor, whereas a Lewis base is the lone pair donor.

Specifically, a Lewis base is defined as a an electron donor.

A base are substances that, in aqueous solution, release hydroxide (OH−) ions.
A Lewis base can donate a pair of nonbonding electrons.
