Veal? Do it perhaps as a joint (8)
I believe the answer is:
dovetail
'a joint' is the definition.
(dovetail is a kind of joint)
'veal? do it perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'veal'+'do'+'it'='vealdoit'
'vealdoit' is an anagram of 'DOVETAIL'.
'as' is the link.
(Other definitions for dovetail that I've seen before include "Joint with fan-shaped tenon" , "good joint" , "Fit closely together like white bird and appendage" , "Interlocking joint" , "Violated (anag) -- mortise joint" .)
