If you want to examine something closely and go over every single detail, then you should scrutinize it. Like the way your mom probably assesses your outfit before you leave the house for school.
Scrutinizing is very different from glancing or gazing. It’s even more than a long, hard look. To scrutinize something, you have to look at it really critically, investigating every nook and cranny. Often things are scrutinized to verify if they’re correct or authentic. So it makes perfect sense that this verb is rooted in the Latin word scrutari, which means “to search.”
