Origins
The English word "compromise" traces its origins to the Latin term "comprōmissum," which itself is the neuter past participle of the verb "comprōmittere." This Latin verb is a compound formed from the prefix "com-" meaning "together" or "mutually," and "prōmittere," meaning "to promise" or "to send forward." The latter is further analyzable into the prefix "pro-" signifying "forward" and the verb "mittere," which means "to send," "let go," or "release." The ultimate root of "mittere" can be linked to the Proto-Indo-European root *meyth₂- or *mit-, which carries the general sense of "to send" or "to throw."
In its original Latin usage, "comprōmissum" referred specifically to a mutual promise by parties involved in a dispute to submit their case to arbitration. This was not yet the sense of settling differences by mutual concessions but rather an agreement to abide by the decision of a third-party arbiter. The emphasis was on the mutual commitment to resolve the dispute through a formal process, rather than on the outcome of concessions or compromise in the modern sense.
The term entered Old French as "compromis," retaining this legal and procedural meaning of a mutual promise to accept an arbitrator's decision. It was from Old French that the word passed into English in the 15th century, initially preserving the sense of a mutual agreement to submit a dispute for arbitration rather than the broader notion of a negotiated settlement.
Modern Usage
The semantic shift toward the contemporary understanding of "compromise" as a settlement involving mutual concessions developed later, primarily during the 16th century. This evolution reflects a broadening from the technical legal context to a more general social and political usage, where parties make concessions to reach an agreement. The idea of "compromise" as a process of give-and-take, rather than simply a promise to abide by an external decision, became firmly established in English usage during this period.
In addition to the noun form, the verb "to compromise" also emerged in English, carrying the sense of settling a dispute by mutual concession. Notably, in the 17th century, the verb acquired an additional, somewhat figurative meaning: "to endanger one's reputation or principles." This sense derives metaphorically from the notion of putting something at mutual risk or exposure, akin to the original idea of placing a dispute in the hands of an arbiter and thus risking an unfavorable outcome. Over time, this figurative use has become common, especially in contexts involving personal integrity or security.
It is important to distinguish the inherited Latin roots and their semantic developments from later borrowings or unrelated cognates. The English "compromise" is a direct descendant of the Latin "comprōmissum" through Old French "compromis," rather than a later borrowing or a calque. The components "com-," "pro-," and "mittere" are well-attested Latin morphemes with clear meanings that combine logically to form the original compound verb "comprōmittere."
French Influence
"compromise" in English originates from a Latin legal term denoting a mutual promise to submit a dispute to arbitration. Its meaning evolved in the 16th century to encompass the broader notion of settling differences by mutual concessions, and in the 17th century, the verb form gained a figurative sense related to risking or damaging one's reputation. The word's etymology reflects a clear lineage from Latin through Old French, with roots deeply embedded in the concepts of mutuality and promise inherent in its Latin components.
