Morphology
efficient = effic + ent
The combining form 'effic' is not a standalone English word and the adjective is a Latinate borrowing, so learners cannot reliably derive the meaning from its parts.
Etymology
Efficient comes from Latin parts ex- 'out' and facere 'to make', and it shares the same root as factory, a place that makes things. So something efficient is good at 'making things happen' quickly and without waste, which is why it means working well while saving time or effort.
