maestro
/maˈestɾo/ · A2 · adj
expert
🎓🔨 From Latin magister (master) — same root as English master and maestro
Latin magister comes from magis, meaning more: the one who is more skilled. The g dropped out in Spanish, leaving ma-es-tro. English borrowed maestro for orchestra conductors, but in Spanish it covers any expert: teacher, craftsman, builder.
