(On Lat. scrutiny).
1. m) Accurate and diligent investigation and investigation that is done for something to form an assessment about it.
2. m) Recognition and counting of votes in elections or other similar events.
It is noteworthy that the word Scrutiny, before being strongly linked to the previously identified meaning, was used as an accurate and diligent examination of a thing, which has not lost this meaning but with very little use. For example: legal scrutiny, medical scrutiny, etc.
Synonyms for scrutiny are investigation, examination, investigation, inquiry, etc.
