Etymology:
- It is a 17th century phrase. The writer who introduced this idiom might have imagined a wagon which got stuck in mud or marsh. In addition to pulling wagon by horse, the driver would also try hard by putting or supporting his shoulders to the back wheels to get the wagon rolling again. Today the expression means to do toil hard to achieve something.
Phrasal verb:
Blast off | Leave the ground- spaceship or rocket. | The space shuttle BLASTED OFF on schedule yesterday. |
