Morphology

work + one's + ass + off

The verb 'work' clearly signals effort, while 'ass' here is a vulgar body-part metaphor serving as an emphatic intensifier and 'off' is non-literal; a learner who knows the constituents can probably infer high effort but not the exact idiomatic sense or register. Because the expression relies on a figurative intensifier and coarse colloquial usage rather than straightforward composition, it is only partially predictable without prior exposure.

Etymology

The idiom work one's ass off gives a strong, slightly rude picture: imagine someone working so hard that their ass is almost worn off. That's why it means 'to work extremely hard'.
