"Skeat" is the winner of a competition by Google, to create a gingerbread house using its program SketchUp, including "dynamic candy" in the construction:
The old version of the OED I have, however, says following Skeat that the English word "gun" may derive from the Norse woman's name Gunhilda given to an ancient artillery piece -- or else from a compound of "gun" + "hilde", approximately, both of which have martial meanings.
Skeat considers the English word was taken from the Welsh _caban_, rather than from the French, and that the original source for all the forms was Celtic.
Incidentally, Skeat pÃ¨re makes no mention here of his close collaboration with J.A. H. Murray on the original Oxford English Dictionary:
Tim, I just looked at the Distributed Proofreaders link Cally posted and boy do I wish I had time to get to the "hard poetry" level in time to proof the Skeat I have sitting on my bookshelf here...and there are pulldown menus for all sorts of diacriticals and things.
