At 16Ac I have a word which can be a monetary note reversed, making an addition which can be made to milk. I can think of a three letter word meaning "steep", which might be relevant (RET), but that leaves me to justify either ENN or NNE. If I didn't know better, I might think the setter was cluing to include some omitted letters and forgot half way through. I'm very confident of my solutions for 10,5,6,7, & 8 Down. I don't know, perhaps the 6 letters I have written in are a synonym for the first word in the clue, which I have been unable to source. Can anyone enlighten me?
