They are seven words in the English language that rhyme with no other words. I'm sitting here and I don't feel like Googling the answer. I have come up with Orange and Purple so far. There are five more, any ideas?
A runt is most commonly an animal unusually small for its kind, especially as applied to pigs. This commonly occurs when a litter is too large for all the newborns to nurse at once, as the weakest will be pushed aside, becoming less nourished and so proportionately smaller over time. For example, in E. B. White's classic Charlotte's Web, Wilbur the pig is a runt.
