single-handedly

The word "single-handedly" is a modern English formation built upon the compound adjective "single-handed," which dates to the early 17th century. It literally describes an action performed with "one hand," implying a lack of assistance from another person or hand. The metaphorical extension from a physical limitation to a mode of independent accomplishment is straightforward. The adverbial suffix -ly is appended to the adjective, following a standard pattern in English for creating manner adverbs, to describe the way an action is carried out.

Structure: single (one) + hand (hand) + edly (adverb suffix) - single: From Latin singulus (one, individual). Functional role: Adjective root meaning "one". - hand: From Old English hand. Functional role: Noun root, used metaphorically to represent agency or action. - edly: A compound suffix from -ed (adjectival suffix forming participial adjectives) + -ly (adverb-forming suffix). Functional role: Converts the adjectival phrase "single-handed" into an adverb.
