Root Breakdown

-splural
=rapids

Originally 'rapid' as a noun meant one fast stretch of river; English settled on the plural rapids as the everyday name for it. This is the family member that keeps the original force of rapere ('to seize, sweep away') — rapids are water that grabs and hurls a boat downstream, not just water that moves fast.
