Sadly I only have one letter and as its the last clue I have no chance of getting any more. The word EDIFICE (building) fits but can't make it fit the other part of the clue
Possibly aconine i.e a + co (company) + nine (less than ten). It's a medical term not sure what it means but it may have something to do with builders in the sense of improving / ptotecting the body.
Hi Crypto - thanks for the suggestion - I can see where you are coming from but still struggling to find a meaning connected to builders. I still keep thinking I am missing something important!
This clue was in the daily mail within the last two weeks. Can't remember what the answer was but there were at least three more given letters and with them the answer was apparent.
Terry - thanks for taking the trouble to reply - as this is the last clue and I am really keen ti finish it I had a quick look around the Daily
Mail online site but it didn't help. Wonder if anyone else out there remembers it?
