Pampered when travelling around island? That's wishful thinking! (4,5)
I believe the answer is:
pipe dream
'wishful thinking' is the definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'pampered when travelling around island?' is the wordplay.
'when travelling' indicates an anagram.
'around' indicates putting letters inside.
'island?' becomes 'i' (geographical abbreviation).
'pampered' with letters rearranged gives 'ppedream'.
'ppedream' placed around 'i' is 'PIPE-DREAM'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for pipe dream that I've seen before include ""Pie in the sky"" , "Fanciful hope" , "Fantastic notion!" , "Fanciful or impossible plan" , "Futile hope" .)
