Morphology

detective = detect (transparent) = detect + ive

Formed by adding the productive adjectival suffix '-ive' to the verb 'detect'; the sense 'relating to detection' and the noun use 'person who detects' are readily inferable.

Etymology

Detective comes from Latin parts de- 'away' and tegere 'to cover', the same root you see in protect. So a detective 'takes away the cover' to find what is hidden, which is why they search for clues and facts.
