Bronsted refers to hydrogen donors (acid) and acceptors (base). Meanwhile, lewis refers to lone pair donors (base) and acceptors (acid).

lewis acids and bases are defined as electron pair acceptors and receptors respectively. bronsted acids/bases are defined in reference to hydrogen donation or receiving, and bronsted acids donate protons and bases receive them

Lewis acids are defined as the electron pair acceptor. Bronsted acids are defined as the proton donor. The Bronsted definition is only used for acids in which the hydrogen ion can transfer between molecules. HCl is a bronsted acid when reacting with water. Since HCl also accepts the electron pair, it is also the Lewis Acid.

A Bronsted acid is a proton donor and a Bronsted base is a proton acceptor, while a Lewis base is an electron acceptor, while a Lewis base is an electron donor. (Bronsted refers to protons while Lewis refers to electrons)

Bronsted acids and and bases refers to the donating and accepting of protons, while Lewis acids and bases refers to the donating and accepting of electrons

A lewis acid/base accepts/donates electron pairs, while a bronsted acid/base donates/accepts protons
