Leon, thank you for all that. I had figured WAY(SI)DE had to be one but couldn't figure the two letter 'function'. I have to say the preamble just did not fit with what was required. There really is no explanation for AFARA and the highlighting thereof. Unless I am mistaken the clues DO NOT have 'the right notes' correctly sequenced - there are two UTs to be removed, a MIS to be replaced by SOL and what on earth the two wrong letters are in TESLA before changing I've no idea. I'm sorry this was a dismal puzzle which a lot of solvers will have binned.
