Morphology

investigation = investigate (transparent) = investigate + ion

The noun is a regular nominalization of the verb 'investigate' using the productive suffix '-ion', so learners who know 'investigate' can predict the meaning.

Etymology

The word investigation comes from Latin parts in- 'into' and vestigium 'footprint' or 'trace'. Think of investigators following footprints to find the truth, so an investigation is a careful search for the facts.
