What does unfeasibly mean?
Unfeasibly is an adverb meaning “in a way that cannot actually be carried out or achieved.” It is used when something is described as impossible, impractical, or beyond the resources or conditions needed to complete it. The adjective unfeasible names the condition; the adverb unfeasibly describes the degree or manner of that condition. Typical expressions include unfeasibly difficult, expensive, or complex. Unlike a neutral negative such as not feasible, the word often carries an emphatic, sometimes mildly humorous tone. It can sound more formal than ordinary alternatives such as impossibly or impracticably, making it useful in technical, academic, and business discussion, though it also appears in everyday criticism of ambitious plans. The formation is transparent: un- adds negation to feasible, while -ly converts the resulting adjective into an adverb. Overall, unfeasibly communicates not merely that an outcome is difficult, but that it may be impossible under the stated circumstances.

Where does unfeasibly come from?
Unfeasibly is the adverbial derivative of unfeasible, formed by combining the negative prefix un- with feasible. Feasible entered English from French faisable, derived from faire, “to do or make,” which ultimately comes from Latin facere, “to make or do.” The same shared root appears in cognate and related forms such as feasible, infeasible, and feasibility.
