10 ac - "Loose cryptic definition?" Loose it certainly is. Never heard the phrase either, more familiar with **** * fashion.
And more looseness.
As a French speaker, I have never used nor heard used the word provided in the solution to mean "worthy".
And who pronounces
the first part of 20 ac the way the clue suggests?
There are others but I'll stop there.
So as not to be seen to be over critical, I did like 12 and 17ac.
