Morphology

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

Formally 'trans-' (through) + the combining root 'spire' (breathe/emit) yields the botanical sense, but the combining root is not a familiar standalone word for many learners.

Etymology

Transpire comes from trans- 'across' and spirare 'to breathe', and the same breathing root is in respire. Think of a leaf 'breathing across' as water leaves its surface, which is why plants 'transpire' by giving off water vapour.
