Morphology

dead + set

The adjective 'dead' can function as an intensifier meaning 'completely' and 'set' carries the sense 'fixed' or 'determined'; combining them yields the straightforward compositional meaning 'completely fixed' or 'firmly determined.' This follows regular English compounding of an intensifier plus adjective/participle, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.

Etymology

Dead set may come from the image of something so firmly fixed it cannot move, with dead suggesting 'completely' and set meaning 'fixed in place'. So, if someone is dead set on or 'against' something, they are very determined and will not change their mind.
