Morphology

ground + zero

The constituents 'ground' (earth surface) and 'zero' (origin point) do suggest a location that is the starting or reference point on the ground, so a learner might infer a literal 'point on the ground.' However, the conventional use to mean the site of a major disaster or attack (originally a nuclear blast point and later extended metaphorically) is a specialized, culture-specific extension that many B1 learners would not fully predict without prior exposure or background knowledge.

Etymology

Ground zero was later used by news people to name the site of a disaster, because the same idea—the single point most damaged—fit other events. So ground zero now often means 'the place where a major disaster happened' or 'the starting point of its effects'.
