  • Meg seeks cwm becks. 'Cwm' is possibly the only English word made solely of prime-numbered letters (bcegkmqsw) that doesn't contain an E. Seriously, does no-one have a list of prime-lettered words . . . or a word for them? (Primogram?)

  • This word came up when my English teacher claimed there were no words without vowels--she was surprised to learn about cwm! Our language hoovers up words from so many places you can find almost any odd example you can think of. I'd like us to start using the Amharic verb "machubchub" to describe the sound of swishing a liquid inside your mouth. :^ )
