Question

Pls tell a story of the idiom
Speaking of the devil

Answer 1

Here is your answer

"Speak of the devil" is the short form of the English-language idiom "Speak of the devil and he doth appear" (or its alternative form "speak of the devil and he shall appear"). It is used when an object of discussion unexpectedly becomes present during the conversation. It can also be used about a topic that quickly becomes relevant, such as the onset of rain or a car breaking down. Used in this sense it can be seen as an alternative to the phrase "tempting fate".
