From Muppet Wiki

This page documents the dubious claim that the word "Muppet" is a combination of "marionette" and "puppet."

Pro

• 1956: "A Muppet according to Henson, is a cross between a hand puppet and a stick puppet. Henson thought up the term Muppet in order to 'have something distinctive.'" (Washington Post, September 2.)

• 1957: "Jim devised the name 'muppets' for his brainchildren, because they're a cross between stick and hand puppets." ("For Jane and Jim, Rollicking Muppets Set a Merry Pace", Katharine Elson, Washington Post and Times Herald, February 17.)

• 1978: "The name Muppet, by the way, was coined by Jim to represent his own individual puppet designs, a combination of 'marionette' and 'puppet.'" (Muppet Show Fan Club newsletter vol. 1, no. 5.)

• 2001: "Jim came up with the name Muppets during the Sam and Friends years -- it is a combination of the words marionettes and puppets." (Jim Henson's Designs and Doodles, Alison Inches.)

Con

• 1971: "The word Muppets is a Henson crosshatching of words moppet and puppets." (All About Sesame Street, Phyllis Feinstein.)

• 1978: "The word was coined from 'marionette' and 'puppet', says Jim Henson, 42, the skinny, bearded Zeus from whose brow the creatures began to spring 20-odd years ago, when he was a teenager hooked on television... Like other geniuses, Henson is a sly fellow whose sound artistic instinct is to resist critical analysis... Now he backtracks and says that "muppet" was simply a word that sounded good to him. The sound combination of puppet and marionette is merely an explanation that happens to sound logical." ("Those Marvelous Muppets", John Skow, Time Magazine, December 25.)

• 1983: "I think we did the term Muppets before we got the show Sam and Friends - a few months after I started working. It was really just a term we made up. For a long time I would tell people it was a combination of marionettes and puppets but, basically, it was really just a word that we coined. We have done very few things connected with marionettes." (Jim Henson, quoted in "Of Precious Pigs, Singing Cabbages, and a Little Green Frog Named Kermit: The Story of Jim Henson and the Muppets", Judith P. Harris, Cinefantastique, April/May.)

• 2001: "My parents came up with this name, 'Muppet,' because it was a funny, cute name... and some people say that they took the two words 'marionette,' which is a string puppet, and 'puppet,' and they put them together. But, we actually think that it's more that my father just thought it was a fun-sounding word." (Cheryl Henson, quoted in A&E Biography: Sesame Street.)
