  • Usage notes

    * The plural rooves'' is uncommon and is considered by some to be incorrect, though it is parallel to more common plurals like ''hooves'' and ''staves. * In referring to the top of a building, refers both to the object itself (“the roof was blown off in the tornado”) and to the location of being on the roof (“it can be dangerous to go on the roof to fix the antenna”). In the later sense (of “location”) it is often used attributively, largely interchangeably with rooftop.
