boathouse singular

boathouses plural

boathouse = boat + house (transparent) = boat + house

The meaning is directly the combination of 'boat' + 'house' (a building for storing/keeping boats), which is easily inferable from the components.

Boathouse is simply made of boat and house, so it literally means a 'house' for boats by the water where you store and protect them.
