thanks, brendan. I've solved the 8 clues and agree that all answers to the clues are real words. My problem is that when the "thematic instruction" is applied only 3 of them are still words, although a fourth is just about acceptable. It's the next stage which eludes me. If the non-words are entered I'm left with two 6-letter entries each with three unches. These are the initial letters of some thematic words - is this a coincidence, or have I stumbled on the way forward? As i posted much earlier, I think I'm overthinking all this.
