It is sometimes said that the words orange, purple, and silver are the only words which rhyme with no other words. However, the following words have been cited as possible rhymes: "door hinge" (even though it consists of two words) and sporange (an alternate form of the word sporangium), curple (another name for the buttocks; in Scots, the word for the hindquarters of a horse), hurple (meaning to walk lamely or to hobble), chilver (which the Oxford English Dictionary lists as an Old English noun meaning a ewe lamb, often referred to as a "chilver lamb", and cites uses as recent as 1883). But there is much debate about some of these words. Some question whether archaic words, or Scottish and dialectal words such as hirple should be counted. More significantly, it is questionable whether the pronunciation of sporange truly rhymes with orange, since the only pronunciation listed in the Oxford English Dictionary has the accent on the second syllable: /spɒ'rændʒ/, roughly "spo-RANDJ".
