Ale there can be heavenly (8)
I believe the answer is:
ethereal
'heavenly' is the definition.
(similar in meaning)
'ale there can be' is the wordplay.
'can be' indicates an anagram.
'ale'+'there'='alethere'
'alethere' anagrammed gives 'ETHEREAL'.
(Other definitions for ethereal that I've seen before include "Take ale there: it's light and delicate" , "'Extremely delicate, almost not of this world (8)'" , "There in lea - it looks delicate" , "Airy or supernatural" , "Delicate - airy" .)
