suspicious
If you are suspicious, you feel that someone is doing something wrong or that something is not right.
Explanation at your level:
If you think something is bad or wrong, you can say it is suspicious. Imagine you see a person hiding behind a tree at night. That is suspicious. You do not trust them. You feel that they might do something bad. It is a word for when you feel worried about a person or a thing. You can say, 'That looks suspicious' when you see something strange. It helps you stay safe by being careful.
When you are suspicious, you do not believe someone. You think they might be lying or doing something illegal. For example, if a stranger asks for your password, you should be suspicious. It is a useful word to describe people, behavior, or even objects. If you see a bag left alone on a train, it is a suspicious object. Always tell someone if you see something that makes you feel this way.
The word suspicious is used to describe a feeling of doubt or distrust. You might be suspicious of your friend's motives if they suddenly act very nice after a long time. It is a common word in news reports or detective stories. You can say, 'The police are investigating suspicious activity in the neighborhood.' It suggests that something is not quite right and needs closer attention. Using this word shows that you are observant and cautious about your surroundings.
In B2 level English, suspicious is used to convey nuance. It isn't just about 'not liking' something; it is about detecting an inconsistency or a potential threat. You might find a situation suspicious because the facts provided don't align with reality. It is frequently used in professional contexts, such as 'The company noticed suspicious transactions in the account.' It implies a need for investigation or verification. It is a powerful adjective that signals you are thinking critically about the information presented to you.
At the C1 level, suspicious can be used in more figurative and subtle ways. You might describe a 'suspicious silence' or a 'suspicious coincidence,' where the lack of action or the timing of an event creates a sense of unease. It is often used in academic or formal writing to suggest that a theory or a set of data lacks credibility. For instance, 'The results of the experiment appeared suspicious, prompting further peer review.' It indicates a high level of skepticism and a sophisticated ability to analyze motives and outcomes. You are not just reacting to a person, but to the logical structure of a situation.
At the mastery level, suspicious is a tool for nuanced social and literary analysis. It can describe a character's disposition, such as a 'suspicious nature,' implying a deep-seated, perhaps cynical, worldview. It can also describe the atmosphere of a scene, creating a sense of foreboding or paranoia. Historically, the word carries connotations of 'looking beneath the surface,' which is a skill refined in C2 learners. You might explore how a suspicious outlook affects interpersonal dynamics in a novel or how 'suspicious' is used in legal rhetoric to challenge the validity of evidence. It is a word that bridges the gap between simple distrust and complex, critical appraisal of the human condition.

Hey there! Let's talk about the word suspicious. It is one of those words that carries a lot of weight in everyday conversation. When you feel suspicious, your internal alarm bells are ringing because something just doesn't feel right.
Think of it as a mix of doubt and curiosity. You aren't sure what is going on, but you definitely feel like you need to be careful. Whether it is a suspicious character in a movie or a suspicious email in your inbox, the core feeling is the same: you are questioning the truth.
It is important to remember that being suspicious isn't always a bad thing. Sometimes, it is just your brain's way of staying safe. It helps you pause, look closer, and ask questions before you jump into something blindly. It is a very useful word to have in your vocabulary when you need to express that feeling of 'something is off here!'
The word suspicious has a fascinating history that takes us back to Latin. It comes from the Latin word suspiciosus, which itself is derived from suspicere. This word literally means 'to look up at' or 'to look under'.
Think about that for a second! In ancient times, if you were looking up at someone or looking under something, you were essentially 'looking out' for danger. Over time, this evolved into the concept of 'looking at something with distrust.' It traveled through Old French as suspicieus before landing in English.
It is a classic example of how our language connects physical actions to complex emotions. By the 14th century, the word was well-established in English to describe that uneasy feeling that someone might be hiding something. It is amazing how a word about 'looking' became a word about 'doubting'!
You will hear suspicious used in many different ways. In casual conversation, you might say, 'That guy looks suspicious,' if he is acting weird in a store. It is very common to use it with nouns, like suspicious behavior or suspicious activity.
The register of this word is quite flexible. It works perfectly in a formal police report—'The officer noted suspicious circumstances'—and it works just as well when you are chatting with a friend about a weird text message you received. It is a standard, neutral adjective that fits almost anywhere.
Common collocations include highly suspicious, very suspicious, and look suspicious. You can also be suspicious of someone, which is a great way to express your personal doubt. Just remember that it is a strong word; using it implies you have a real reason to be concerned, not just a passing thought.
Idioms often use the concept of suspicion to describe social situations. 1. To smell a rat: This means you suspect something is wrong. Example: 'I smelled a rat when he offered me a deal that was too good to be true.' 2. Raise an eyebrow: To show surprise or suspicion. Example: 'His sudden change in story raised a few eyebrows.' 3. Take with a grain of salt: To be suspicious of the truth. Example: 'Take his promises with a grain of salt.' 4. Fishy: Something that seems dishonest. Example: 'That whole situation sounds a bit fishy to me.' 5. Keep tabs on: To watch someone suspiciously. Example: 'The guard was keeping tabs on the visitors.' These expressions help you sound more like a native speaker when discussing doubt.
Grammatically, suspicious is a straightforward adjective. It is not a count noun, so you don't use articles like 'a' or 'an' directly before it unless it is part of a noun phrase, like 'a suspicious character.' It is often followed by the preposition 'of' when describing the person feeling the emotion.
Pronunciation-wise, it is sə-SPI-shəs. The stress is on the second syllable. A common mistake is to mispronounce the 'cious' ending; remember it sounds like 'shus,' not 'see-us.' Rhyming words include ambitious, delicious, vicious, nutritious, and fictitious. Practice saying these to get the rhythm down!
In terms of patterns, you will often see it used as a predicate adjective: 'The package seemed suspicious.' It is a versatile word that rarely changes form, making it quite learner-friendly once you master the stress pattern.
