the word 'surging' originates from the present participle of the verb 'surge'. the root 'surge' derives from the latin verb surgere, meaning 'to rise', which itself is a contraction of subrigere, from sub- ('up from below') and regere ('to lead straight, guide'). this literal sense of a powerful upward movement evolved into the modern abstract meanings of a sudden, large increase or a forceful, wave-like motion. the suffix '-ing' marks its function as a verb form describing an ongoing action or state.

Structure: surge (to rise) + ing (present participle suffix) surge (from latin surgere, meaning 'to rise'), ing (from old english -ende, present participle suffix)
