Morphology

ketone = acetone (opaque) = ket + one

The word is a specialized chemical name built using the combining form 'ket-' and the chemical suffix '-one'; these components are not meaningful to general B1 learners.

Etymology

The word ketone comes from the common chemical name acetone plus the ending -one, which chemists used to name this type of chemical. So ketone means chemicals like acetone, and in the body ketones are made when fat is broken down for energy.
