I heard someone say 'speak of the devil' at work—what exactly does it mean in conversation?

Asked byAmelia EditorPosted Apr 1, 2026 2:33 AM3 answers13 upvotesCanonical URL

Today at work, I walked into the break room just as my coworkers were talking about me, and one of them said, 'Speak of the devil!' I was surprised and a bit confused because I wasn't sure if it was a negative comment or just a joke.

I've also seen this phrase used in movies, and I want to make sure I understand it before using it myself. For example, is it correct to say, 'Speak of the devil, here you are!' when someone you were just talking about suddenly appears? Or is it only used in specific situations?

Context:
British English, casual conversation

The phrase 'speak of the devil' follows a familiar conversational pattern in English used when the person being discussed appears unexpectedly. This is not typically meant as an insult but is a playful way to acknowledge the coincidence.

Pattern:

["Speak of the devil!"] + [person being discussed arrives]

Example 1:

  • You're talking about Emma, and she walks in. You say: "Speak of the devil! Hello, Emma."

Example 2 (contrasted):

  • If Emma is not the person you were discussing (for instance, you were talking about lunch plans), you wouldn't use the phrase. Saying "Speak of the devil!" in that context would confuse your listener.

Practice:
Try inserting the phrase when someone you were just talking about enters the room: "Speak of the devil, here you are!"; but avoid using it if the person wasn't the recent topic.

Self-check:
When using 'speak of the devil,' ask yourself, "Was I just talking about this person?" If yes, it's the right context.

Think about the timing when you use 'speak of the devil'. This phrase fits when someone enters a scene just as they become the topic of conversation. It signals surprise and coincidence, not criticism.

Let’s guide your usage:

  • Example 1:
    • Two people are discussing Jane's weekend plans. Jane then enters. They say, "Speak of the devil, Jane! We were just talking about you."
  • Contrast Example:
    • If Jane walks in and you weren't talking about her, saying "Speak of the devil" wouldn't be correct. Instead, you could simply greet her: "Hi, Jane."

Try this:
The next time you notice this coincidence, use the phrase and reflect—was the person a recent topic?

Self-editing tip:
After you use the phrase, ask yourself whether it made sense in context. If not, think of a more suitable greeting for next time.

'Speak of the devil' is an informal English phrase used when someone appears just after being mentioned in conversation. It's normally light-hearted and not offensive. To see how it works, let's compare it with another phrase:

  • Correct usage:
    • You and a friend are talking about your boss. Suddenly, your boss enters, and you say, "Speak of the devil!"
  • Incorrect usage for clarification:
    • You say, "Speak of the devil!" when someone enters, but no one was talking about them before. In this case, it doesn't make sense, and your listener might be confused.

A similar phrase is, "Look who just showed up!" However, that doesn't have the "we were talking about you" implication.

Practice:
Next time you're chatting about someone, try using 'speak of the devil' only if they walk in while you're speaking about them.

Correction tip:
If you mistakenly use 'speak of the devil' when you weren't talking about someone, simply switch to a general greeting like "Oh, hi there!"
