Morphology

blackbody = black + body (semi-transparent) = black + body

The components 'black' and 'body' are clear, but the sense is a specialised physics concept (an ideal absorber) not fully deducible by an average learner.

Etymology

Blackbody is made from black and body: black here means 'not reflecting light' and body means 'physical object'. So a blackbody is an ideal object that absorbs every kind of light and then gives off light only based on its temperature, which is why scientists use it to study the light hot things make.
