Titchfield, you are brilliant. I deliberately left out the G of running and you filled it with O(G)YGIAN. I thought the second clue was TRUCE but didn't know why. I'm Scottish so knew Weans but am too old to remember the playground!
I'm going to chance my arm once more with:
M.O.'s M.O. (6,7). I have RE?OA? S?NS?N?
I'm thinking of Medical Officer's Modus Operandi but might be far off the beam.
Titchfield, thank you once again. Next week I shall just send you a copy of the whole crossword! I did eventually find Telergy, by the way, but in a crossword dictionary, not an ordinary one.
