Herb used to relish getting around top lawyer (6)
I believe the answer is:
lovage
'herb' is the definition.
(I know that Lovage is a type of herb)
'to relish getting around top lawyer' is the wordplay.
'to relish' becomes 'love'.
'getting around' is an insertion indicator.
'top lawyer' becomes 'ag' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'love' placed around 'ag' is 'LOVAGE'.
'used' acts as a link.
Can you help me to learn more?
(Other definitions for lovage that I've seen before include "Herb made from a glove" , "Salad plant from southern Europe" , "F" , "Herb and salad plant" , "Salad plant from a glove?" .)
