How it's used
Carries a formal and serious tone, often appearing in news reports or official statements regarding accidents, corruption, or public policy failures. Unlike everyday verbs, it implies a comprehensive, deep-dive process that leaves no stone unturned. It is rarely used in casual conversation between friends unless discussing serious societal issues.
Examples
The government must thoroughly investigate this scandal.
Have you all decided to investigate it thoroughly to the end?

Common phrases
investigate thoroughly to the end
thoroughly investigate the truth
Common mistake
Do not use this for casual checking or looking into minor personal matters, as it sounds overly dramatic and bureaucratic. For everyday situations like checking a schedule or looking for lost keys, use 睇下 or 檢查 instead.
