Etymology
The word 'joust' entered English in the 13th century from the Old French verb 'jouster', meaning 'to approach, to meet, to joust'. This Old French term derived from the Vulgar Latin 'iuxtare', a verb based on the Latin adverb 'iuxta', meaning 'near, close to'. The semantic evolution is beautifully logical: from the basic concept of drawing near, the word specialized in the context of knights meeting in combat. The modern abstract meaning retains this core idea of a formal, one-on-one contest or confrontation, directly descended from the literal act of two armored horsemen charging close together.
Analysis
The word 'joust' is a simplex loanword from Old French. Its spelling and form are not productively composed of smaller, meaningful English morphemes.
