Etymology
The term "most-favored-nation" is a modern legal and diplomatic compound, constructed from core English words of diverse origins to express a precise contractual concept. "Most," of Germanic origin, establishes a superlative degree. "Favored," from the Latin 'favor' via French, implies preferential treatment. "Nation," also from Latin via French, specifies the recipient entity as a sovereign state. The phrase's logic is entirely compositional: it literally means "the nation receiving the greatest preference," which directly maps to its modern use in international trade agreements, where it guarantees a country the lowest tariffs offered to any other trading partner.
Analysis
Structure: most + favored + nation
most: From Old English 'māst', meaning greatest in amount or degree. It functions as a superlative adverb/adjective.
favored: From Old French 'favor', from Latin 'favor' (goodwill). The '-ed' suffix forms a past participle, meaning 'regarded or treated with preference'.
nation: From Latin 'natio' (birth, race, people), via Old French. It functions as a noun meaning a large body of people united by common descent, history, culture, or language, inhabiting a particular state or territory.
