overwhelming

The word 'overwhelming' is built on the verb 'overwhelm,' which entered Middle English from the fusion of the intensifying prefix 'over-' and the now-archaic verb 'whelm,' meaning to cover or submerge, especially with water. 'Whelm' itself has Germanic roots, likely related to the Old English word for an overturned container. Thus, the literal sense is of being utterly engulfed or turned over by something from above. Over centuries, this concrete image of a flood or wave completely covering something evolved into the modern abstract meaning of being overpowered by a great force, intensity, or amount, whether physical or emotional.
