Two questions
Question No. 1. four letters: clue "Most of layered rock forming thin strip"
I am not sure which of these is preferable? SLIT or SLOT (SL?T)
Question No. 2. eight letters: clue "It's to do with marriage of Constance with cooler Albert."
I reckon that "conjugal" fits, but I'm not sure how or why (con-jug-al): ?O?J?G?L)
Clarification much appreciated !
