The German verb “lassen” is a main verb under the category of strong verbs (unregelmäßige Verben). It is one of the few special verbs in german language. This is due to it‘s numerous characteristics which include having two forms of Partizip II (lassen and gelassen) and being used with other infinitives without the use of “zu”. With regards to context, lassen can have a variety of meanings both in German language as well as when translated to English.

Different meanings of the verb lassen

Originally, lassen means “to let” or “to leave” in English and it’s used in the following instances;

1. Ich lasse mein Auto im Park.—— I am leaving my car in the park.

2. Warum will sie dich lassen?—— Why won’t she let you?
Lassen as let and leave

When used with other infinite verbs, lassen is usually best translated as “to let” and has up to four contextual meanings as seen below…

1. To not take something along

GermanLiteral translation

Fifth meaning of lassen

In this case, lassen is used together with other verbs as an alternative for the wir-imperative form of german verbs. Here lassen is always conjugated to the third-person subject (er/sie/es) and supported by the first-person plural direct object pronoun (uns) to mean “let us” while the other verb goes to the end of the sentence in its infinite form. They both have similar meaning in English but that with lassen sounds better and is most often used. For example, see the comparison between “wir-imperative” and “lassen + infinitive imperative”.

Lassen + Infinitive in Perfect Tense

Lassen as a strong/unregelmäßige Verben, forms it’s Partizip II (which is a key component in forming the perfect tense) with “ge”. When lassen is used with other infinitive verbs in the perfect tense, it loses the prefix “ge”. Instead of the usual haben + gelassen, it becomes haben + Infinitive + lassen. For example;

Perfect without “ge-“Perfect with “ge-“
1. Ich habe mich imfen lassen.

2. Max hat sein Handy reparieren lassen.

3. Hast du dein Handy zu Hause aufladen lassen?
Ich habe mich beim Impfen gelassen.

Max hat sein Handy beim Reparieren gelassen.

Hast du dein Handy zu Hause beim Aufladen gelassen?
