That is exactly what held me up crates, until I read the intended interpretation on here - most frustrating !
If you plug the possible letters from the first 4 clues into wordfinder
([swpa][osdt][rtn][ogdn]), the following words are possible:
pond pong porn song sord sorn word worn
I had made an educated guess that the first word would be 'song' or 'word', but of course had no way of knowing for certain that the first word in the message was not shorter than 4 letters, and on that basis didn't have the will to proceed - thank goodness for this site !
