aliado
/aˈljado/ · B1 · adj
a confederate
🤝🔗 aliado = ally + -ado: someone allied, bound to you (Latin ligare, to bind)
Spanish aliar and English ally both come from Latin alligare, to bind to. The same root ligare gives ligament, the tissue that binds bones. An aliado is someone bound to your cause, and the -ado ending matches the -ed in allied.
