Well placed to distribute dope around the islands (6)
I believe the answer is:
poised
'well placed' is the definition.
'poised' can be an answer for 'placed' (poising is a kind of placing). I'm not sure about the 'well' bit.
'distribute dope around the islands' is the wordplay.
'distribute' indicates an anagram (I've seen this in other clues).
'around' means one lot of letters goes inside another.
'the islands' becomes 'is' (i is an abbreviation for island).
'dope' with letters rearranged gives 'poed'.
'poed' enclosing 'is' is 'POISED'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for poised that I've seen before include "Ready for action or self-assured" , "Balanced and composed" , "Balanced or braced" , "Showing self-assurance" , "Balanced or self-assured" .)
