Leeren vs. ausleeren vs. entleeren
While leeren, ausleeren, and entleeren all translate to "to empty" in English, German distinguishes between the general state of being empty, the physical action of dumping something out, and the technical or medical process of draining something.
Leeren
B1This is the most general and somewhat formal way to say "to empty." It focuses on the result (the container becoming empty) rather than how it is done. It is often used for drinking vessels, official containers like mailboxes, or abstract concepts like clearing one's mind.
Der Kellner leerte die Flasche in die Gläser der Gäste.
(The waiter emptied the bottle into the guests' glasses.)
Der Postbote leert den Briefkasten jeden Werktag um 17 Uhr.
(The mail carrier empties the mailbox every workday at 5 PM.)
Ich gehe spazieren, um meinen Kopf zu leeren.
(I go for a walk to clear my head.)
Ausleeren
A2This verb is very common in everyday spoken German. The prefix aus- implies specific movement: "out." It emphasizes the physical action of tipping a container over, dumping contents onto a surface, or turning something inside out to remove what is inside.
Kannst du bitte den Mülleimer in der Küche ausleeren?
(Can you please empty the trash can in the kitchen?)
Er leerte seine Taschen auf dem Tisch aus, um den Schlüssel zu finden.
(He emptied his pockets out onto the table to find the key.)
Nach dem Strandbesuch mussten wir den Sand aus unseren Schuhen ausleeren.
(After the visit to the beach, we had to dump the sand out of our shoes.)
Entleeren
B2This is a sophisticated, technical, or medical term. It implies a formal process of draining, discharging, or evacuating a system. You will mostly hear this regarding machinery, tanks, batteries, or bodily functions.
Bitte entleeren Sie den Wassertank vollständig, bevor Sie das Gerät reparieren.
(Please empty the water tank completely before repairing the device.)
Der Patient wurde gebeten, seine Blase für die Untersuchung zu entleeren.
(The patient was asked to empty his bladder for the examination.)
Mein Handy-Akku hat sich über Nacht im kalten Auto entleert.
(My phone battery drained inside the cold car overnight.)
Summary
Use ausleeren for casual, physical actions where you dump or tip things out (like trash or bags). Use entleeren for technical, official, or medical contexts (like tanks, batteries, or biology). Use leeren as a neutral or slightly more elegant term for consumption (drinks) or abstract concepts (mind).
