The word is derived from a Dravidian language, and it passed through numerous other languages including Sanskrit and Old French before reaching the English language. The earliest uses of the word in English refer to the fruit, and the colour was later named after the fruit. Before the English-speaking world was exposed to the fruit, the colour was referred to as "yellow-red" (geoluhread in Old English) or "red-yellow".
It is claimed that the word orange has no true rhyme. There are, however, several half rhymes or near-rhymes, as well as some proper nouns and compound words or phrases that rhyme with it. This lack of rhymes has inspired many humorous poems and songs.
