Morphology

amorphous = morphous (semi-transparent) = a + morph + ous

If 'morphous' is known, adding privative 'a-' gives the straightforward sense 'without form'.

Etymology

Amorphous comes from the Greek parts a- 'not' and morph 'shape', so it literally means 'without shape'. Think of glass or fog that has no fixed form, and you will remember why scientists call such materials amorphous.
