Morphology

endothermy = endotherm (semi-transparent) = endo + therm + y

The noun is formed by adding '-y' to a recognizable technical base 'endotherm', a standard nominalization pattern.

Etymology

Endothermy comes from endo- meaning 'inside' and thermy meaning 'heat', the same root in thermometer and thermal. So in chemistry endothermy means heat moves 'into' the reaction or object, which is why the container can feel colder.
