Hi Brendan,
I think 16 appeared in Paul's recent Prize magnum opus, with a different spelling.
Thanks to Everyman, I found this tougher than last week's but not unusually challenging.
FOI 6, COD 14 over 12. LOI 2, which I found a bit dubious.
14 parses as hearing (7) + "little thing..."* (3).
*could be positive or negative :-)
I'm having trouble parsing 11, pretty sure of answer.
Happy to see the "first letters" clue.
