Just finished, with 9a being my last one in. But can't parse it at all! don't see any mention of it by others, so I'm probably missing something obvious.
I agree this was an enjoyable solve over my Sunday brunch. Some useful gimmes and some slightly trickier. I’m choosing 11a as my WOD (word of the day that I want to use more often) - a lovely loan word that I will try to fit into my week somehow.
