From the word’s history
From Middle English investigacioun, from Old French investigacion, from Latin investigatio; investigate + -ion.
源自拉丁文 investigatio，即 investigate 加 -ion。
You can picture investigation as a careful, official looking-into: something has gone wrong or is unclear — a crime, an accident, a problem — and someone steps in to dig under the surface, collect facts, and pin down what really happened. It is not a casual glance but a deliberate, organised search for the truth.
