Board member from Balearic Islands opens retail opportunity (6)
I believe the answer is:
bishop
'board member' is the definition.
(I've seen this before)
'balearic islands opens retail opportunity' is the wordplay.
'opens' says to take the initial letters.
'retail opportunity' becomes 'shop' (I can't explain this - if you can you should believe this answer much more).
The first letters of 'balearic islands' is 'bi'.
'bi'+'shop'='BISHOP'
'from' is the link.
Can you help me to learn more?
(Other definitions for bishop that I've seen before include "Chess piece and senior religious person" , "that, moving, must abandon his rank" , "see supervisor" , "Powerful cleric" , "He wears the mitre and carries the crozier" .)
