Grammar & Word origin

The word einschalten is a separable verb (trennbares Verb). This means that in a standard main clause in the present or simple past tense, the prefix ein- moves to the end of the sentence. Its principal parts are:

Present: schaltet ein
Simple Past: schaltete ein
Past Participle: eingeschaltet

The word is a compound of the prefix ein, which indicates a movement into something or the initiation of a state, and the base verb schalten, which means to switch, to shift gears, or to govern. The origin of "schalten" relates to the pushing or shoving of a bolt or lever.
