Morphology

quaternionic = quaternion (transparent) = quaternion + ic

The adjective is clearly formed from the noun 'quaternion' with the productive adjectival suffix '-ic' meaning 'relating to'.

Etymology

The word quaternionic comes from quaternion, which originally means 'a set of four' — think of a quartet, a group of four musicians. Quaternions are numbers with four parts used in math and 3D graphics, so quaternionic means 'about those four-part numbers'.
