Morphology
extravasation = extravasate (semi-transparent) = extra + vas + ation
Formed by nominalization of the verb 'extravasate' using a Latin-derived suffix; the prefix 'extra-' (outside) is recognizable but the root 'vas' (vessel) is a specialist combining form not known to most learners.
Etymology
Extravasation comes from extra- 'outside' and vas 'vessel'. So think of lava or fumes pouring out of their 'container', which is why extravasation means lava or fumes flowing out from a volcano.
