The first practical application of runcification was in 1871 when Edward Lear noted that a runcible spoon could be used by owls and pussycats.
"They dined on mince, and slices of quince, Which they ate with a runcible spoon," from The Owl & The Pussycat.
In subsequent years Lear applied the principles of runcibility in other fields:
"He has gone to fish, for Aunt Jobiska's Runcible Cat with crimson whiskers!"
Modern students of runciosity believe that it may have been inspired by the word "rouncival" (apparently meaning gigantic).
