It seems my last answer 21d pin on Daniel regularly must be nail but my brain can't work out
where Daniel and regularly fit in
Pleased to offer answer to Shaney Star who usually comes up trumps when I'm stuck

[shaneystar]

Well it has to be nail(pin) wendy but I can't justify it really.Only that nail is in the word daniel. It's not as if the word comes from every other letter ie. regularly.Sometimes RT is a bit ambiguous !! Thanks for the other answer.

[johnalex]

[shaneystar]

Well done johnalex. I couldn't see that for the life of me!!
Thank you.
