Definition of annexe

The word "annexe" has its origins in the Latin word "annectere," meaning "to tie on" or "to attach." It was borrowed into French as "annexer," meaning "to annex" or "to add to." The English word "annexe" first appeared in the 17th century, initially meaning "something added or attached." It came to refer to a building or room added to a larger structure, likely due to its original sense of "adding" or "attaching." Today, "annexe" primarily denotes an extension or additional building connected to a main structure.
