Morphology
equipollent = equi + pollent
The prefix 'equi-' clearly signals 'equal', but the root 'pollent' is not a productive English morpheme and the precise technical sense is specialized, so the meaning is only partially deducible by average learners.
Etymology
Equipollent comes from Latin parts equi- 'equal' and pollent 'powerful', like the English word potent which means 'powerful'. So, it literally means 'equal power', which helps explain why it describes things that have the same force or effect.
