Competitively → It is formed from "competere" (from Latin, meaning to strive together) and the suffix "-ively" (meaning in a manner). The word "competitively" describes the manner of striving together in a contest or rivalry.
Think of people 'striving together' ('competere') in a contest, and the '-ively' shows how they do it — that's why competitively means doing something in a competitive way.
