Morphology

afterdamp = damp (opaque) = after + damp

Although formed from 'after' + 'damp', 'damp' here has a technical/archaic mining sense 'vapor/gas', so learners who know ordinary 'damp' (moist) will not infer the toxic-gas meaning. [Postprocessing: moved 'after' from base_words to prefix]

Etymology

Afterdamp combines after and damp, where damp once meant 'vapour' or 'gas' in mining rather than just 'a little wet', so afterdamp is the dangerous mix of gases left in a mine 'after' an explosion.
