Out of the blue

Something that suddenly and unexpectedly occurs.



The "blue" in the phrase refers to the sky, one from which a sudden thunderstorm is unexpected. A related phrase “a bolt out of the blue” tends to confirm this explanation.

Ex: That goal was a real bolt out of the blue. The game was almost boring up until now and now it’s alive!



Spanish: de la nada



German: plötzlich hereingeschneit kommen
