I'm stuck!
I've got the grid filled in apart from 2 letters in 22 down. I've got (i think) the shared thematic definition. But I'm having trouble with the 'pairs of letters' I've got pairs for most clues, but they make gobblededook!!! As for the phrase - my ODQ is nearly thumbed to bits!!
I'm sure this is far more simple than I'm making it.
Please could some kind person point me in the right direction before I tear my hair out!
Thanks in advance.

Phrase is not in ODQ!
Remind me of 22d!
Phrase(s) not familiar to me - not into Pratchett!!!
Shared thematic definition = technical term for male b-----, part of perimeter phrase that starts at C
More??

Remember that the pairs will join up, not just stay as pairs -I think it began 'wh en yo uh av', so that becomes 'when you hav...' I didn't get it from the Pratchett thing, but from the 'non-English' quote.

Just wondering. Was it a clever part of the theme that the extra letters came in pairs?

[Ripper]

Got it!
Thank you all
Yes boreas they come in pairs!!!!!

Apart from Hitler, of course.

Know what you mean. I started out going that spelling route.
