Usage tips
Separable verb
'Einlassen' (to get involved / let in) is a separable verb. In a main clause, the prefix 'ein-' stands at the end. In subordinate clauses or in the infinitive with 'zu', the verb stays together.
EXAMPLE
Der Bademeister lässt das Wasser ins Becken ein.
The lifeguard lets the water into the pool.
Reflexive with preposition
In this meaning, the verb is always reflexive and is used with the preposition 'auf' and the accusative. The fixed structure is: 'sich auf etwas/jemanden einlassen' (to get involved in something/with someone).
EXAMPLE
Sie wollte sich nicht auf eine Beziehung mit ihm einlassen.
She didn't want to get involved in a relationship with him.
Context clue: object
The meaning changes depending on the object: a reflexive pronoun ('sich') means 'to get involved.' A person as the object ('jemanden') means 'to grant someone entry.'
EXAMPLE
Er lässt sich auf das Experiment ein.
He gets involved in the experiment.
Crafts context
The meanings 'etwas einbauen' (to install something) or 'eine Oberfläche behandeln' (to treat a surface) are used almost only in a crafts or trades context. Pay attention to words like wood, stone, oil, or wax.
EXAMPLE
Der Schreiner hat die Scharniere sauber in die Tür eingelassen.
The carpenter set the hinges neatly into the door.

einlassen vs wachsen
to grow / to wax
'wachsen' and 'einlassen' can both mean treating a surface so that it is protected. 'wachsen' means treating something with wax, for example skis or a floor. 'einlassen' is used especially with wood, when oil, wax, or glaze soaks into the material. Learners may confuse the words because wax can be involved in both. The important difference is: 'wachsen' names the substance, wax, while 'einlassen' describes more that a liquid soaks into a surface.
einlassen
Nico hat den Holztisch mit Öl eingelassen.
Nico treated the wooden table with oil.
wachsen
Vor dem Skiurlaub wachsen wir die Skier im Keller.
Before the ski vacation, we wax the skis in the basement.
