Morphology

collapsibility = collapsible (opaque) = collapse + ible + ity

In the statistical sense the technical meaning ('invariance under aggregation') is a specialized metaphorical extension not directly inferable from the physical sense 'to collapse'.

Etymology

Collapsibility comes from the word collapse, which itself comes from Latin parts com- 'together' and labi 'to fall', so it originally means 'able to fall together'. In statistics, collapsibility is the idea that a measure stays the same when you bring groups together, which is why the origin helps explain the modern meaning.
