A ceiling is an overhead interior surface that bounds the upper limit of a room. Generally not a structural element, but a finished surface concealing the underside of the floor or roof structure above.

A cathedral ceiling is any tall ceiling area similar to those in a church.

A dropped ceiling is one in which the finished surface is constructed anywhere from a few inches to several feet below the structure above it. This may be done for aesthetic purposes, such as achieving a desirable ceiling height; or practical purposes such as providing a space for HVAC or piping. An inverse of this would be a raised floor.

A concave or barrel shaped ceiling is curved or rounded, usually for visual or acoustical value, while a coffered ceiling is divided into a grid of recessed square or octagonal panels, also called a lacunar ceiling.
