I. TheoryIn English, the verb “to leave” has a rather wide range of meaning. In German, there are several verbs that mean “to leave” but have different nuances. Some always take an object while others do not.
|Mein Nachbar musste sein Haus wegen eines Brandes verlassen.|
My neighbor had to leave his house due to a fire.
Wenn ich ins Büro gehe, lasse ich meinen Hund in der Küche.
When I go to the office, I leave my dog in the kitchen.
In the first example above, verlassen is conveying “leave” in the sense of “leaving behind/abandoning.” In the second sentence, lassen means to “leave (a direct object) in a particular state/location”.
