Morphology

transpire = spire (semi-transparent) = trans + spire

The physical sense 'pass through' can be related to 'trans-' + 'spire', but learners who don't recognise the combining root may not derive it easily.

Etymology

Transpire in this sense comes from trans- 'across' and spirare 'to breathe'. Imagine a gas 'breathing across' a fabric or skin and moving through tiny holes, and you can see why it means to pass through a surface.
