No, this isn’t my attempt at Diamond Geezer-style cryptics.
Last year I got up to the 10-or-more answers per day stage on the Guardian crossword, though I’m pretty rusty at the moment. As an attempt to kick some life into my miserable crosswording, I was browsing a guide to cryptic crosswords when I saw the clue above given as an example.
It mentioned, in passing, that the apostrophe-s here is the link word (i.e. the word that links the definition with the cryptic explanation). Apostrophe-s = “is”, in crossword-speak.
I never realised that. How bad at these things am I?
Q: Does this make sense?
A: Jon heads off, backtracking negatively (2)
