Pass on after last of bone extracted from joint (5)
I believe the answer is:
refer
'pass' is the definition.
(I've seen this before)
'on after last of bone extracted from joint' is the wordplay.
I cannot quite see how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found within the answer.
'last' could be 'f' (I've seen this in other clues) and 'f' is found within the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for refer that I've seen before include "Advert, cite" , "Direct elsewhere" , "guide" , "Pass" , "Draw attention" .)
