This is great, the official reasoning behind the IUPAC animo acid one-letter codes is based on a lot of the ways I originally memorised them.
W is the bulkiest letter for the bulkiest residue, and lysine was assigned K because it's the letter before L.

@multimeric Neat! I wonder what the “linguistic reasons” for avoiding J are?
@johannes_lehmann @askennard @multimeric
Maybe it's because J can be pronounced Huh or Yuh or Juh depending on language.
@askennard @multimeric
Maybe that J is a derivative of I (j and i used to be the same letter, just stylistic variants) - and in many typefaces they are difficult to distinguish?
