#concave

• Abud — A rare regional or archaic term used to describe an object, container, or domestic space that is hollowed out, deeply concave, massive, or disproportionately bulged. In certain isolated vernacular dialects, the adjective can also refer to a primitive landform or a rudimentary natural shelter, retaining a connotation linked to archaism, solidity, and raw utility in the peasant household of yesteryear.
