Thanks for the link to that amazing Times difficulty site, quisling.
I do The Times crossword only when I go to bed, so I felt some trepidation last night (Friday) having seen the 140 level of difficulty. I did eventually manage it. I thought of PARAPH overnight but had to check it on my phone - a new word for me. Pleased to have worked out PRONUNCIAMENTO without help, having been delayed by thinking 'soon' was going to be 'anon' rather than 'pronto'.
Another meaning I discovered in Thursday's was LIST meaning 'border' referring to the fence round a jousting arena. So that's what's meant by 'entering the lists' - never realised.
