Usage

What does suspicion mean? Suspicion is the state or act of suspecting something—having a sense that it may be true without knowing with certainty. Suspicion can also refer to this sense, as in I had a suspicion that I was going to be fired, or an instance of suspecting someone of something, as in My suspicions turned out to be right—they had been stealing from the register. A suspicion 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. Suspicion is most commonly used in negative contexts, but this isn’t always the case. For example, you might have a suspicion that someone is planning a surprise party for you. Suspicion can also refer to a state of mind, as in He’s always been prone to suspicion. To regard something with suspicion is to regard it with distrust. Sometimes, suspicion refers to the state of being suspected, especially of a crime or other wrongdoing. This sense of the word is often used in phrases like under suspicion and on suspicion of, as in He was arrested on suspicion of robbery. Someone who’s considered highly trustworthy might be described as above suspicion, meaning you would never suspect them of doing anything wrong. The adjective suspicious can describe a person who has suspicions about others, as in My parents got suspicious when I kept asking whether they’d be home tomorrow, or someone or something that arouses suspicion, as in a suspicious package. Example: We have suspected it all along, and what happened today confirmed our suspicions.

Synonym Usage

Suspicion is the positive tendency to doubt the trustworthiness of appearances and therefore to believe that one has detected possibilities of something unreliable, unfavorable, menacing, or the like: to feel suspicion about the honesty of a prominent man. Distrust may be a passive want of trust, faith, or reliance in a person or thing: to feel distrust of one's own ability.

Etymology

Origin of suspicion

First recorded in 1250–1300; Middle English, from Latin suspīciōn- (stem of suspīciō ), equivalent to suspīc- (variant stem of suspicere “to look from below, suspect” ) + -iōn- -ion; see suspect

Explanation

Suspicion is a feeling that something might be true. If your friends seem to be keeping a secret from you, you might have a suspicion that they are planning a surprise party for your birthday. Suspicion can mean the same as hunch or inkling, like when you have a suspicion that your friend is hiding a flower bouquet behind his back. Suspicion comes from the Latin word suspicere, or mistrust. That's why it can mean a general bad feeling about someone or something, like neighbors who regard all new people with suspicion until they get to know them.
