Did You Know?
"Multitudinous" is one of many English words that make use of the combining form "multi-," from Latin "multus," meaning "many." "Multicolored," "multifunctional," and "multimillionaire" are just a few of the others. "Multitudinous" is the kind of highly expressive word that you can rely upon when you want something a little more emphatic than plain old "numerous." Among its synonyms are "multiple" and "multifold," two more members of the "multi-" family.
