The sense evolution is from the old belief that Egyptian mummies were embalmed with asphalt, which was used medicinally in medieval times. Ancient mummies were harvested for asphalt they were thought to contain, and later merchants mummified executed criminals and other unclaimed bodies to supply the trade. Abd al-Latif al-Baghdadi, traveling in Egypt circa A.D. 1300, reported buying three mummified heads filled with asphalt for half a dirham. This medicinal mummia or mummie also was used as a paint pigment into early 20c.ETD mummy (n.1).3

The infectious disease probably was so called in reference to swelling of the salivary glands of the face and/or to painful difficulty swallowing. Mumps also was used from 17c. to mean "a fit of melancholy, sullenness, silent displeasure."ETD mumps (n.).2

mun (v.)

Munchkin (n.)

1900, coined by U.S. author L. Frank Baum (1856-1919) in "The Wonderful Wizard of Oz." He never explained how he got the word.ETD Munchkin (n.).2

(It comes from Middle Dutch mutseken, originally "a little cap," from mutse "cap," earlier almutse "amice, hood, headdress," from Latin amictus "mantle, cloak," noun use of past participle of amicire "to wrap, throw around," a compound from ambi- "around" (see ambi-) + iacere "to throw" (see jet (v.)).ETD Munchkin (n.).3

Latin mundus "world" was used as a translation of Greek kosmos (see cosmos) in its Pythagorean sense of "the physical universe" (the original sense of the Greek word was "orderly arrangement"). Like kosmos (and perhaps by influence of it), Latin mundus also was used of a woman's "ornaments, dress," which also could entangle the adjective mundus "clean, elegant."ETD mundane (adj.).3

The English word's extended sense of "dull, uninteresting" is attested by 1850. Related: Mundanely. The mundane era was the chronology that began with the supposed epoch of the Creation (famously reckoned as 4004 B.C.E.).
