The phrase "file in circular file" is often used to mockingly tell someone to throw a document in the trash. The spelling of "file" is straightforward, with the IPA transcription being /faɪl/. However, the addition of "circular file" adds a layer of humor and irony to the phrase. "Circular" is pronounced as /ˈsɜːrkjələr/, while "file" is still pronounced the same. The phrase gains a certain degree of wit by using a more formal term for a wastebasket to describe throwing something away.
"File in circular file" is an idiomatic expression that refers to the act of discarding or disposing of a document, record, or piece of information, typically by throwing it in the trash. The circular file is a metaphorical term for a wastebasket or trash can.
This expression is used humorously or cynically to imply that the information or document being discarded is considered unimportant, irrelevant, or of no value. It suggests that the document will be immediately discarded without further consideration or potential for future use.
The phrase is often used in informal contexts, such as conversations or casual writing. It can be employed to convey a sense of dismissiveness or to downplay the significance of something. For example, if someone receives an email with a proposal that they have no intention of considering, they may say, "I'll just file that in the circular file," implying that they will simply discard it.
The phrase is believed to have originated in the mid-20th century and has become a well-known idiom over time. It serves as a lighthearted way to indicate that something is being intentionally disregarded or disposed of, emphasizing a lack of importance or value.
