The quality or capacity of being able to be coiled or wound up into loops.
From 'coil' (a loop or series of loops) + '-able' (capable of) + '-ity' (the quality of being). The suffix chain creates a noun describing the property itself.
Coilability matters enormously in manufacturing—it's why certain plastics work for rope while others shatter, and why springs are engineered with specific metallurgical properties.
