verb

anlassen

leave · start

The German word "anlassen" is a separable verb made up of the prefix "an" (meaning "on" or "at") and the verb "lassen" (meaning "to let" or "to allow").

Meaning:
"Anlassen" commonly means:

  • To start (especially machines or engines, e.g., "den Motor anlassen" = "to start the engine").
  • To leave on or keep running (e.g., a light or a device).
  • It can also mean to initiate or to begin something.

Similar words:

  • starten (to start)
  • einschalten (to switch on)
  • laufen lassen (to let run)

Differences:
While "starten" means to start something (like an engine or program), "anlassen" often implies starting and possibly continuing to let it run without interruption. "Einschalten" focuses more on switching on devices or lights, not necessarily implying the device keeps running autonomously as with "anlassen".
