the quality or state of being fractuous; a tendency toward fracturing, breaking, or splitting; roughness or irregularity of surface with many breaks.
From fractuous (adjective, meaning inclined to fracture) + -osity (suffix forming abstract nouns from adjectives). Both derive from Latin fractus (broken).
Geologists describe rock fractuosity when analyzing whether stone will fracture in regular patterns or irregular ones—this determines how usable the stone is for construction and how natural resources like oil can be extracted.
