Morphology
The meaning 'a reaction that absorbs energy' is directly and compositionally derived from combining 'endoergic' (involving absorption of energy) with 'reaction' (a chemical/nuclear process). This adjectival + noun construction follows regular English morphology and semantics, so a learner who knows both constituents can infer the MWE meaning.
Etymology
Endoergic reaction comes from two word parts: endo- meaning 'inside' and -ergic meaning 'work' or 'energy'. Imagine the reaction pulling energy into itself so energy moves 'in' rather than out. That's why the term means a nuclear reaction that 'absorbs' energy.
