Munificent is an adjective but can also be used as a noun, munificence, or an adverb, munificently and means very generous—as in a very generous person. Munificent is derived from the Latin word munificus (generous); however, munificus is derived from the Latin word munus (gift, service). Munus also give rise to the terms municipal and remunerate.
First used in the late 1500’s, it’s thought that the word munificent was formed by combining the word magnificent with the word munificence.
