​ADJUNCT (from Lat. ad, to, and jungere, to join), that which is joined on to another, not an essential part, and inferior to it in mind or function, but which nevertheless amplifies or modifies it. Adverbs and adjectives are adjuncts to the words they qualify. Learning, says Shakespeare, is an “adjunct to ourself” (Love’s Labour’s Lost, IV. iii. 314). Twelve members of the Royal Academy of Sciences in Paris are called “adjuncts.”
