Morphology

intumescence = tumescence (semi-transparent) = in + tumescence

Formation is the same (in- + tumescence), but the technical/materials-science sense ('increase in volume when heated') is a specialized extension of 'swelling', making it less directly inferable for average learners.

Etymology

Intumescence comes from the Latin parts in- 'in' and tumescere 'to swell', the same root as tumor, so it literally means 'swelling'. That's why the word is used for materials that expand or 'puff up' when heated, as a protective swelling on a surface.
