This article is about an architectural structure. For the large tree root, see Buttress root. For slang, see buttocks.
A buttress is an architectural structure built against (a counterfort) or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of the roof structures that lack adequate bracing.
The word buttress, in a much more general sense, means to support; one might buttress another person's argument, for instance. By visual analogy, that which looks like a buttress may be called so; eg Buttress root at the base of the trunk of a tree.

Terminology
In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the corner, and a diagonal (or 'french') buttress is at 45 degrees to the walls.[1][2]
