Nonchalant synonym,synonyms of nonchalant

Similarity: Both "nonchalant" and "indifferent" convey a sense of lacking strong interest, concern, or emotion. For example, if a person is nonchalant or indifferent about a situation, they show little reaction or care. Someone might be nonchalant/indifferent about the outcome of a game, not showing much excitement or worry.
Usage difference: "Indifferent" often implies a more general lack of interest or concern across a wider range of things. It can be used to describe a person's overall attitude towards many different topics or situations. "Nonchalant" usually refers to a more specific display of casualness or coolness in a particular moment or situation, often with an air of being unruffled or unconcerned about something that might otherwise cause stress or excitement.

Similarity: "Apathetic" shares the sense of not showing much feeling or concern with "nonchalant". They both describe a state where a person seems not to care or be involved. For instance, an apathetic/nonchalant person might not bother to take action in a situation that requires attention, showing a lack of enthusiasm or motivation.
Usage difference: "Apathetic" often has a more negative connotation and implies a deeper, perhaps more concerning lack of emotion or interest. It can suggest a sense of lethargy or a general unwillingness to engage, often due to a lack of belief in the importance of something or a feeling of helplessness. "Nonchalant" is more about a surface-level casualness or coolness, and may not carry the same sense of deep-rooted disinterest or hopelessness.

Similarity: "Casual" and "nonchalant" both imply a lack of formality or a relaxed attitude. A nonchalant person often behaves in a casual way, showing a relaxed demeanor and not being overly concerned about details or appearances. For example, someone might dress in a casual manner or have a casual approach to a task, similar to how a nonchalant person would handle things without much fuss.
Usage difference: "Casual" is a more general term that can describe behavior, style, or attitude in many different contexts. It can refer to something being informal or not serious in a broad sense, like "casual conversation" or "casual clothing". "Nonchalant" is more focused on a person's emotional or psychological state of being calm and unconcerned in a particular situation, especially when there might be an expectation of more concern or reaction.

Similarity: In the sense of being calm and collected, "cool" is similar to "nonchalant". A cool person, like a nonchalant one, can remain calm and composed in the face of stress or excitement. For example, in a tense situation, someone might stay cool/nonchalant and not show any signs of being flustered.
Usage difference: "Cool" has a broader range of meanings and can also refer to something being fashionable or attractive, which is not a meaning of "nonchalant". When used to describe a person's attitude, "cool" can imply a certain level of self-possession and confidence, sometimes even a bit of detachment. "Nonchalant" specifically emphasizes the lack of concern or worry more than the aspect of self-confidence or being in control.

Similarity: "Detached" and "nonchalant" both suggest a sense of being removed or not fully engaged. A detached person, like a nonchalant one, may seem to stand apart from a situation and not be overly involved or affected by it. For instance, someone might have a detached/nonchalant attitude towards the drama going on around them, not getting emotionally involved.
Usage difference: "Detached" often implies a more deliberate or conscious separation from something, perhaps due to objectivity or a desire to remain uninvolved. It can be used in a more intellectual or emotional sense, like being detached from one's emotions or being detached in an analysis. "Nonchalant" is more about the outward display of casual unconcern and may not carry the same sense of a thought-out or purposeful detachment.
