Morphology

pay + dirt

The phrase links 'pay' (to yield profit) with 'dirt' (earth) via a metaphor from mining — literally earth that ‘pays’ because it contains valuable ore — so there is a recognisable relation to the constituents. However, this metaphorical, domain-specific sense and the noun formation are not fully predictable for a B1 learner who only knows the literal meanings, making comprehension partial rather than straightforward.

Etymology

Pay dirt comes from mining. When miners dug up earth that gave them money, they called that soil pay dirt because the dirt 'paid' them. That's why it means 'earth or ore that brings money'.
