Hi Malone.
I need some help here! If 35 a is the Scottish word for dust, I don't see what suffix you could add to it which would make any sense. Perhaps I need some help getting the theme too!
35a works well with a single letter suffix - its even in Chambers. Am also at sea with the theme and down clues - - I think the suffix is four letters which works with some of them but not some others. Gtfl help. Tks v much

To finish and be satisfied I need to parse my solution. I cannot decide whether the first and last letters are identical (a/e ?) . Dealing with the unchecked letters has been somewhat tedious in this cleverly constructed puzzle.
