Morphology

effusion = effuse (transparent) = effuse + ion

This sense denotes the literal physical act of flowing or pouring out described by 'effuse', so the nominalization is direct and clear.

Etymology

Effusion comes from Latin parts ex- 'out' and fundere 'to pour', so it means a 'pouring out'. That's why in science and medicine an effusion is fluid or gas that has 'poured out' into a place it should not be, like fluid in the chest.
