A theoretical or specialized concept relating to water structures that have elbow-like joints or angles; or a system based on aquincubital principles.
From 'aquincubital' plus the suffix '-ism' (a system, practice, or doctrine), created as an abstract noun to describe a practice or theory based on aquincubital characteristics.
This word is almost certainly not used outside of very specialized technical contexts—it represents how scientists can build any theory or practice into an '-ism,' even if only three people in the world would ever use the term!
