Etymology: This adjective is formed by combining the prefix "non-" with the base adjective "feasible." The prefix "non-" is a straightforward negator in English, borrowed from Latin through Old French, used to indicate the absence or negation of a quality. It became a productive way to form antonyms in English from around the 15th century onward. The root "feasible" itself entered English in the late 16th century, coming from the French "faisable," meaning "that may be done," which derives from the verb "faire," meaning "to do" or "to make." This verb traces back to Latin "facere," carrying the same meaning. Over time, "feasible" came to mean "possible to accomplish" or "practicable." Putting the two parts together, the term simply denotes something that is not possible or not practical to carry out. While "nonfeasible" follows the logical pattern of English word formation, it is relatively rare compared to other negations like "infeasible," which serves the same function but is more commonly used. "Infeasible" also comes from Latin via French, with the prefix "in-" serving as another negator. Thus, this word's history stems from the layering of classical Latin roots and common English prefixes to express impracticality or impossibility, reflecting how English builds new adjectives through straightforward combinations rather than borrowing entirely new terms.
