Part of Somerset here, alluring and heavenly (8)
I believe the answer is:
ethereal
'heavenly' is the definition.
('ethereal' can be similar in meaning to 'heavenly')
'part of somerset here alluring' is the wordplay.
'part of' says the answer is hidden in the clue.
'ETHEREAL' can be found hidden inside 'somerset here alluring'.
'and' acts as a link.
(Other definitions for ethereal that I've seen before include "Heavenly - fairy-like" , "Light, airy or spirit-like" , "Insubstantial, other-worldly" , "Of the spirit" , "Like fairies" .)
