reesetee What you may be missing here, Leximaniac, is that the list owner can do whatever he or she wants with whatever words he or she chooses. So the fact that you are talking about compound words made from three words may have no bearing on what the list owner wants to include.
Of course, you're always free to start your own list with different rules. :-) Mar 24, 2010
Leximaniac We are actually talking about compound words made up from 3 words to form the end result. If we ascribe to bilby's notion then every word is multi-compound since each letter can be used to denote something else, even reference to pulp fiction novels. I mean come on... :) Mar 19, 2010
bilby Yes, thanks.

dontcry What about ta? Yes, no? Mar 18, 2010
bilby There's also pent, as in "All my pent-up ridiculosityness bursts forth like an exploding toad whenever I come near Wordnik."
Then there's Agra, which is a city in one of the (can't remember) curry countries.
And finally there's M, which is a number for telephonic murder services.
Easy. Mar 18, 2010
gangerh Is pen not a word? Is tag not a word? Is ram not a word? Mar 18, 2010
Leximaniac How is this a 3 part word? This is made out of penta from "pente", meaning five in Greek and gram from "grammes", meaning lines (in Greek. There is no 3rd part in this word. Now if it was pentadiagram I could concurm since then we could say that the second part is the compound word diagram from diagramma (dia + gramma). I think "pentagram" should not be in this list though. Mar 18, 2010
