And everything else about this place is otherworldly (8)
I believe the answer is:
ethereal
'is otherworldly' is the definition.
(I've seen this in another clue)
'and everything else about this' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'rea' (I've seen this in other clues) and 'rea' is found within the answer.
The remaining letters 'ethel' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'place' acts as a link.
Can you help me to learn more?
(Other definitions for ethereal that I've seen before include "'Extremely delicate, almost not of this world (8)'" , "Exquisite - as light as air" , "exquisitely airy" , "Ultra-refined" , "Insubstantial or heavenly" .)
