A lord’s leaping around at the back (6)
I believe the answer is:
dorsal
'at the back' is the definition.
(I've seen this before)
'a lord's leaping' is the wordplay.
'a lord's' can be anagrammed to 'DORSAL'.
But, I'm unsure how this is indicated.
'around' acts as a link.
Can you help me to learn more?
(Other definitions for dorsal that I've seen before include "(Of fin) on upper side" , "Kind of fin" , "On the upper back" , "'On the back, a fin on a fish perhaps (6)'" , "On the back, fin on a fish say" .)
