A runcible spoon is a funny-looking spoon that has three curved sides and a pointed tip. It's a lot like a regular spoon, but instead of being round or oval, it's shaped like a triangle. The word "runcible" is actually made up, so it doesn't really mean anything.
Now, you might be wondering what makes a runcible spoon different from a regular spoon. Well, for starters, it's not really used for eating. It's more of a novelty item or a prop in stories and poems. Think of it like a silly hat or a funny toy.
The runcible spoon is most famous for its appearance in the poem "The Owl and the Pussycat" by Edward Lear. In the poem, the owl and the pussycat go to sea in a "beautiful pea-green boat" and bring along a "runcible spoon." They use the spoon to eat "mince and slices of quince" and have a jolly good time.
So, to sum up: a runcible spoon is a strange-looking spoon that isn't really used for eating. It's more of a fun item to have around or a silly thing to talk about in a poem. And if you ever go on a boat ride with an owl and a pussycat, you'll definitely want to bring one along!
