Morphology

collisional = collision (transparent) = collide + ion + al

The adjective is formed regularly from the noun 'collision' with '-al', so the meaning 'relating to collisions' follows directly.

Etymology

Collisional comes from the verb collide, which comes from the old parts com- 'together' and a root meaning 'to strike', so imagine two objects 'hitting together'. That's why collisional describes processes caused by things hitting or bumping into each other.
