Surface Forms

Morphology

acellular = cellular (semi-transparent) = a + cell + ular

The meaning is directly 'not cellular', but the scientific privative prefix 'a-' is less familiar to many learners than everyday negative prefixes like 'un-'.

Etymology

The word acellular is formed from the prefix a- meaning 'not' and the familiar word cell, the small unit that makes living things. So, acellular means 'without cells' or 'not made of cells'.
