The word is made up of 'Motor' (engine) and 'Haube' (hood / cover). A 'Haube' is a covering or lid. 'Motorhaube' is therefore literally the cover for the engine of a car.

In connection with the hood, the verbs 'öffnen' (to open), 'schließen' (to close), 'aufmachen' (to open), or 'aufklappen' (to flip open) are often used.

'Haube' and 'Motorhaube' can both refer to a cover. 'Haube' is the more general term and can refer to various covers, for example in the kitchen or on machines. 'Motorhaube' is much more specific: it is the hinged cover over the engine compartment of a car. The words can be confused because 'Motorhaube' contains the word 'Haube'. But when talking about a car, 'Motorhaube' is clearer and more natural. 'Haube' on its own can mean something else in many situations.
