Arroyo comes from Spanish, meaning a small stream or brook, particularly one that is dry except in the rainy season. The term is derived from the Latin word 'aqua' (meaning water) and 'rivus' (meaning brook or stream).
Think of a small 'stream' or 'brook' in Spanish, which helps you remember that 'arroyo' refers to a small watercourse.
