Thank you so much to everyone who replied, especially factor 30 and SeaJayPea for Clatto. I just live along the road from there - I should have got that! Majeyx
Cheers Majey. I'd never heard of it but I just netted out RIVER and couldn't make anything from the remainder that, so I then took out RESERVOIR instead and it left ACLOTT. So I put that in the universal anagram solver and it gave me CLATTO
