How do I use the word lassen as a main verb and auxiliary?

What Does lassen Mean?

At its core, lassen means “to let,” “to allow,” or “to leave.” However, its meaning and usage can shift depending on context. As a main verb, it often conveys permission or the act of leaving something. As an auxiliary, it helps form causative constructions, similar to “to have something done” in English.

Using lassen as a Main Verb

When lassen is used as the main verb, it usually stands alone and often means “to leave,” “to let,” or “to allow.” Here are some common ways it is used:

1. To Leave Something or Someone

This usage expresses that something or someone is being left in a place or state.

In the imperative form, lassen can be used to make suggestions or requests, often translated as “let’s” in English.
