acordar
/akoɾˈdaɾ/ · A2 · verb
to agree
🤝 a- + cor (heart) + -dar: bring hearts together, same root as accord
From Latin ad + cor, cordis (heart): to bring hearts into line, so to agree or settle a plan. English accord is the same word. The carpentry sense follows the same logic: two surfaces brought into agreement sit flush and level.
