#### Usage notes

* Note that the English phrases "to let someone do something" and "to make someone do something" both translate into German as jemanden etwas tun lassen. In order to avoid ambiguity, "to let" can be expressed as jemandem erlauben, etwas zu tun or zulassen, dass jemand etwas tut, while "to make" can be expressed as jemanden dazu bringen, etwas zu tun or dafür sorgen, dass jemand etwas tut.
* In perfect tenses, lassen + infinitive takes a double-infinitive construction, i.e. both verbs are in the infinitive: Ich habe mir die Haare schneiden lassen. (“I’ve had my hair cut.”). However, colloquially, gelassen may also be used.
