noun, adjective, verb, pronoun, prepositional phrase- but most typically, a noun. Someone or thing that is an idiot. He, she, or it, is beyond idiot status that he, she, or it cannot be described as an idiot, but only as a DIGMOND.
Pronunciation: similar to saying almond. No need for an emphasis in the "mond" part of the word, ie: digMOND.
WOW, Kathleen, Matt, Alli, and Liz are such digmonds...
