At the risk of repeating myself… another great puzzle from Monk. Thank you Monk.

I write these posts to help people get started with cryptic crosswords. If there is something here you do not understand ask a question; there are probably others wondering the same thing.
Thanks PeeDee
I think you have an error at 6dn. Your parsing leads to WEEN (E in NEW reversed) not WEAN. I entered TEEN – NET (clear) around E (English) reversed (uprising).
Should 6D be “teen”? — given that to clear is also to net, as in a salary after taxes, around E (English). Otherwise I read the blog as “new” around “a”, which seems to leave “English” out of the equation. Maybe I’m missing something.
@1 Gaufrid — thanks for confirmation. And to PeeDee for blog, without which I could not parse 26A.
Strangely, my first 6 answers all contained the letter F and I wondered if this would be thematic. It proved not to be, so I’ve no eff-in clue (pardon the fr-ench) of any theme. I also wrote WEAN for 6d but couldn’t parse – TEEN of course. Other than that, I did cheat to get 12a – a tough but fair clue. Great stuff, thanks to all.
Yes, I got in a muddle on 6dn. I will fix the blog later.
Lovely stuff from Monk as to be expected. And from his past form, I always go looking for that little extra something but of course he is not obliged to put his moniker on every puzzle, But they are all good.
Thanks all.
I too started off thinking that the letter F would feature throughout but soon gave up on that one. There are three lurking rats in there to accompany the ferret, but that may be just coincidence
Thanks to Monk for a nice brain-stretching and to PeeDee for the explanations
Nice puzzle with some nice devices.
I don’t usually do the FT puzzle these days, but I made the effort to get a copy when I heard that Monk was today’s setter. Well worth doing so. Many thanks.
Thanks Monk and PeeDee
Interesting and challenging crossword as we’ve come to expect from this setter. A wide variety of devices used that had as much work in the word play as seeing the definitional solution in most clues. In particular, FETA, FILTRATE and FERRET (my last in) took me much longer to work out the ‘how’ as the ‘what’.
Thanks PeeDee and all other bloggers for nice comments. I had no idea this had already come out, hence my late visit. The Nina-spotters nearly got it: my notes say “Every answer contains at least one F and/or one T”! If it’s of any comfort, “hidden” Ninas such as this elude my memory by the time they’re blogged! Merry hung parliament to one and all.
