What a fun Everyman this was, quite tricky in places but with enough of the usual anagrams, initial letters, and hiddens to help navigate us through the sticky patches.
I don't know if these count as rhyming pairs but there are some answers with common endings, other than that I didn't notice any theme.
1a and 9a both took an age to parse and, in fact, in 9a I couldn't even initially see a definition! But a scroll through the dictionary sorted everything out:-)
COD - I had initially picked 19d with its "neglected corporation" but was then tickled by the toothless Yankee in 18d and, once I'd finally figured out the wordplay, also thought 1a was worthy of an honourable mention.
Thanks to Everyman for fun and challenging puzzle.
Leave us a comment letting us know how you got on and, if you do get stuck, just post you query on here - there will always be someone on hand to help.
Stay safe:-)
