Having a soft, boggy, or marshy quality; more quaggy than something else.

The word 'quaggier' is derived from 'quag' (from Middle English *quagge*, meaning a bog or marsh) and the comparative suffix '-ier' (meaning more). Therefore, 'quaggier' refers to something that is more boggy or marshy in nature.
Think of a 'quag' as a boggy area, and when something is 'quaggier', it means it is even more like a bog or marsh.
