autoantibody singular

Morphology

autoantibody = antibody (semi-transparent) = auto + antibody

The word is transparently built from 'auto-' meaning 'self' plus 'antibody', but the full medical sense is somewhat specialized.

Etymology

Autoantibody has the part auto- meaning 'self' and the parts anti- meaning 'against' and body meaning 'body'. So an autoantibody is an antibody that attacks the body's own tissues.
