Etymology
Came into English from Middle English avowen, from Old French avouer, from Latin advocare, meaning “to call to, call upon, hence to call as a witness, defender, patron, or advocate”, itself from ad, “to”, and vocare, “to call”. It is a doublet of advoke, avouch and advocate, but is not related to vow.
