The figurative usage of "cast a chill" is closely related to the concept of creating a sudden change in atmosphere or mood, resulting in a feeling of tension or discomfort among those involved. It is often used to describe situations that introduce an element of negativity or foreboding.

Examples of "cast a chill" can be found in various forms of media, including literature, film, and news articles.

This shows how the idiom can convey the immediate impact of someone's presence or actions on the overall atmosphere and emotional state of people.

"Cast a chill" is a relatively common idiom in contemporary English, particularly in informal and conversational contexts. Its widespread usage suggests that it resonates with speakers as an effective way to capture and communicate the idea of creating a negative or uncomfortable atmosphere.

The exact origins of the idiom are unclear, but it is likely that it emerged from the meanings associated with the words "cast" and "chill," as well as the broader cultural associations with these concepts. The act of casting something in a negative or unsettling manner aligns with the notion of projecting or creating an atmosphere of discomfort. Similarly, the concept of a chill can evoke feelings of coldness, discomfort, or unease, which are metaphorically transferred to the emotional or psychological realm when used in this idiom.

Despite the uncertainty surrounding its origins, the continued usage and resonance of "cast a chill" in everyday language highlight its enduring appeal and relevance. The idiom captures the ability of language to convey complex emotional experiences, providing a concise and evocative means of expressing the creation of an uncomfortable environment or atmosphere.

"Cast a chill" is related to several other idioms, including "make someone's blood run cold," "cast a shadow," and "give someone the cold shoulder."

"Make someone's blood run cold" is a similar idiom that describes the act of causing extreme fear or horror in someone. It suggests that something has had such a profound impact on an individual that it sends shivers down their spine and causes their blood to turn cold. While "cast a chill" focuses more on creating unease or discomfort, "make someone's blood run cold" implies a deeper level of fear or horror.

"Cast a shadow" is another related idiom that conveys the idea of creating a sense of gloom or darkness over a situation or relationship. It often implies the presence of something negative or ominous that taints the overall atmosphere. While "cast a chill" is more focused on creating discomfort or unease, "cast a shadow" emphasizes the impact on the overall mood and feeling surrounding the situation.

"Give someone the cold shoulder" is an idiom that means to intentionally ignore or reject someone in a cold or unfriendly manner. It often involves refusing to acknowledge or interact with the individual, creating a sense of isolation or exclusion. While "cast a chill" can create discomfort or unease in a situation, "giving someone the cold shoulder" specifically describes the act of deliberately alienating someone.
