Morphology

antibody = body (semi-transparent) = anti + body

The word is transparently built from anti- + body, but its specialized immunological meaning is not fully predictable from the parts alone.

Etymology

The word antibody comes from anti- 'against' and body 'body', so it literally names something that acts 'against' things that enter the body. Think of the same anti- in antibiotic or antivirus: an antibody is a protein that fights germs like bacteria and viruses to protect you.
