Usage

What does suspicious mean? To be suspicious is to have a suspicion about someone or something, especially to have a feeling of distrust about the person or thing. To be suspicious of someone most often involves suspecting that they are engaged in some wrongdoing, as in My parents became suspicious of me when I kept asking whether they’d be home tomorrow.The word is commonly used to describe a person who is suspicious of someone or something in a specific situation. Sometimes, though, it’s used to describe a person who’s suspicious in general—meaning that they’re generally skeptical or distrustful. It can also be used to describe something, such as an action, that indicates that a person is suspicious, as in She gave me a suspicious look that meant she knew I was up to something.Suspicious can also be used to describe someone or something that causes suspicion, as in The guards are trained to identify suspicious people, suspicious behavior, and suspicious packages.Being suspicious is usually based on something, such as a hunch or some kind of evidence, but the word is typically used in situations in which there is some doubt—when someone suspects something, but isn’t sure. The same thing is implied by the verb suspect and the noun suspicion.Suspicious is most commonly used in negative contexts, but this isn’t always the case. For example, you might be suspicious that someone is planning a surprise party for you.Example: Police are encouraging citizens to alert the authorities if they see any suspicious activity on the subway.
