Limitless adventure holiday thousands of miles away? (4)
I believe the answer is:
afar
'miles away?' is the definition.
(far away)
'limitless adventure holiday' is the wordplay.
'limitless' says to take the centre.
'adventure holiday' becomes 'safari'.
The middle of 'safari' is 'AFAR'.
'thousands of' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for afar that I've seen before include "from baseline to baseline?" , "beyond the horizon" , "long way back" , "Pull out at a distance" , "(From/at) a great distance" .)
