Superior group of islands, UK, maybe getting prior access? Delusion! (13)
I believe the answer is:
hallucination
'delusion' is the definition.
(I know that delusion can be written as hallucination)
'superior group of islands uk maybe getting prior access?' is the wordplay.
I cannot really understand how this works, but
'superior' could be 'u' (I've seen this in other clues) and 'u' is located in the answer.
'of' could be 'o' and 'o' is found in the answer.
'islands' could be 'ci' (I've seen this in other clues) and 'ci' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hallucination that I've seen before include "Trip" , "Illusion" , "Illusory perception" , "Mental aberration" , "Alleged perception of non-existent things" .)
