Morphology

anastigmat = astigmatism (semi-transparent) = an + astigmat

Formally built with a negative/privative prefix 'an-' applied to the astigmat- root, but comprehension requires technical knowledge of 'astigmatism' and the Greek privative.

Etymology

Anastigmat comes from the Greek parts a- meaning 'not' and stigma meaning 'point' or 'mark'. So an anastigmat is a lens that 'does not' turn tiny points into blurry lines, which is why it corrects astigmatism and makes very sharp point images.
