single-mindedly

The word is a modern English compound formed from three distinct elements. The adjective 'single', with its Latin root meaning 'one', combines with the Old English noun 'mind', referring to the intellect or purpose. The suffix '-ed' attaches to create the adjective 'single-minded', literally meaning 'having a single purpose or focus'. Finally, the adverbial suffix '-ly' is added, a productive Germanic formation, to describe the manner of an action. Thus, the etymological logic moves from the concept of 'one thought' to describing a state of undivided attention, and finally to the manner of performing an action with such focus.

Structure: single + mind + edly - single: From Latin singulus (one, individual). Functions as an adjective meaning 'one only' or 'unitary' in this compound. - mind: From Old English gemynd (memory, thought). Functions as a noun meaning 'faculty of thought and consciousness'. - edly: A combination of the adjectival suffix -ed (having the quality of) and the adverbial suffix -ly (in a manner of). Together, they convert the adjective 'single-minded' into an adverb.
