Well, what is a #"Lewis Base"#?

Explanation:

And by definition a #"Lewis Base"# is an electron-pair donor. Now the electron pair is conceived to be donated to an electrophile in a nucleophilic substitution reaction...and this is precisely what occurs in such a reaction....

#underbrace(HO^(-) + H^+)_"Lewis base + Lewis acid" rightleftharpoons H_2O(l)#
