Origin of headlong

First recorded in 1350–1400; Middle English hedlong, earlier hedling; see head, -ling 2

Explanation

Headlong describes something done headfirst, rashly, or really quickly. If you’re the star batter on your baseball team, it’s expected that you'll make a headlong dive for the base. Headlong can refer to hasty actions, but it can also be used more figuratively to describe decisions that are reckless or made in a hurry. Your sister may tend to weigh all the options, but you make headlong decisions. When you decided headlong to move to Florida for a chance to play professionally, your sister thought you’d gone off your rocker — but the day you sign a major contract, she’ll be singing a different tune.
