Gilfach- one of the things I do is I have a small book, indexed as for phone numbers. When someone gives an answer that has an element I haven't met before, I add it to the book. I'm thinking of, for example "judge" in a clue can mean the letters "REF", "flower" frequently means a river, "sailor" can mean AB or tar or RN.
Keep at it, very good for the brain!
