Surface Forms

Morphology

bolt + from + the + blue

The phrase evokes the image of a 'bolt' (like lightning) coming out of a clear 'blue' sky, so the notion of something sudden and unexpected is inferable from the constituents. However, the specific idiomatic collocation 'bolt from the blue' and its conventional use for an unexpected event make it partly conventionalized and not fully predictable for a B1 learner without prior exposure.

Etymology

The expression `bolt from the blue` may come from the image of a bright bolt of lightning suddenly coming from a clear blue sky where no storm was expected. That's why it means 'a sudden and unexpected event'.
