My whole world has come crashing down.
Apparently, the ageless rumor that orange doesn’t rhyme with any other word is (unfortunately?) incorrect. Orange rhymes with Blorenge (a mountain in Wales) and sporange (a technical word for a sac where spores are made). Now I don’t know how well those would go in a song or a poem.
“I went hiking up Mount Blorenge,
in search of the elusive juicy orange,
but I ended up getting deadly ill
as I stepped into a sporange”
But there are words without a rhyming partner. Bulb comes from the Ancient Greek word for onion, bolbas. In the early 1800s, the word was applied to scientific instruments of a similar shape, including the thermometer bulb and the light bulb. It still hasn’t found a word to rhyme with though.
And, then there’s the rhymeless angel, which comes from the Greek word, angelos, which meant “messenger of God.” Finally, the common -th ending takes on many different pronunciations, but the one used for the word month renders it without a rhyming partner.
