Morphology

endothermic + reaction

The adjective 'endothermic' literally denotes taking in or absorbing heat, and when combined with 'reaction' yields the compositional meaning 'a reaction that absorbs heat from its surroundings.' This is a predictable scientific compound built from transparent morphological elements, so a learner who knows both constituents can derive the MWE meaning.

Etymology

Endothermic reaction comes from two old word parts: endo meaning 'inside' and thermic meaning 'heat'. Imagine the reaction as something that takes in warmth from its surroundings, so it means 'a reaction that absorbs heat'.
