Escurrir vs. drenar vs. desaguar
While escurrir, drenar, and desaguar can all be translated as "to drain," they describe different types of action. Escurrir usually involves wringing out or drip-drying, drenar implies drawing liquid out through a system or channel (often technical or medical), and desaguar focuses specifically on emptying water out of a container or space.
Escurrir
B1This verb is used when you squeeze an object to extract liquid, or when you let an object rest so gravity removes the remaining liquid. Think of it as wringing out or straining.

Drenar
B2This word is often more technical. It refers to eliminating excess fluid (or abstract concepts like energy) through a specific channel, pipe, or natural process. It is common in medical, agricultural, and mechanical contexts.
