The problem became knottier as we tried to find a solution.
Knottier → The word 'knottier' is derived from 'knot' (from Old English 'cnotta', meaning a tied or interlaced structure) and the comparative suffix '-ier' (meaning more). Thus, 'knottier' refers to something that has more knots or is more tangled than something else.
Think of a 'knot' as something tied or tangled, and remember that 'knottier' means having more knots or being more tangled.
