speak of the devil

Idioms

The person just mentioned has appeared, as in Why, speak of the devil—there's Jeannie. This expression is a shortening of the older Speak of the devil and he's sure to appear, based on the superstition that pronouncing the devil's name will cause his arrival on the scene. The figurative use was already explained in James Kelly's Scottish Proverbs (1721).
