Morphology

astereognosis = stereognosis (opaque) = a + stereo + gnosis

For learners who know the technical noun 'stereognosis', the medical negative prefix 'a-' fairly clearly signals absence, though this prefix is not very familiar outside specialist vocabulary.

Etymology

The word astereognosis breaks into a- 'not', stereo- 'solid', and -gnosis 'knowing', as in the word diagnosis. So it really means 'not knowing solid things', which is why it names the condition of being unable to recognize objects by touch.
