Talking last evening to a friend about this song, it struck me that I've never been exactly sure what the word "Wime" means though I've sung the lyric often enough. 'The auld grey mare lay on her wime,' I've always thought to refer to a horse lying on its side. What else could it lie on? stomach, back? It would surely SIT on its haunches. Suddenly I'm consumed with self-doubt. Tell me, am I right?! Wime - a horse's side/flank - True or Bluff?
