More example sentences

"Headlong" appeared in Middle English as "hedlong," an alteration of the older "hedling" or "hedlynge." "Hedling" is a combination of the Middle English "hed" ("head") and "-ling," an adverb suffix which means "in such a direction or manner." Thus, "hedling" originally meant "with the head foremost" or, if you will, "in the direction of the head." By the late 1400s, influenced by its use in the compound word "endlong," the adjective "long" began to be regarded as a suffix and a variant of "-ling." It was this substitution of "-ling" with "-long" that led to the replacement of words like "sideling" and "headling" with the now more familiar "sidelong" and "headlong."
