Morphology

accuracy = accurate (transparent) = accurate + acy

Formed from the adjective 'accurate' with the standard noun-forming suffix '-acy' meaning 'the quality of being accurate', so the meaning is directly derived.

Etymology

Accuracy comes from a Latin root that means 'care' — the root cura means 'care', and the word originally meant something done with care. So, accuracy means being correct and exact because careful work brings you close to the true answer.
