Delectable doctor embraced by a sailor at sea (9)
I believe the answer is:
ambrosial
'delectable' is the definition.
(thesaurus)
'doctor embraced by a sailor at sea' is the wordplay.
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus**).
'embraced by' means one lot of letters goes inside another.
'at sea' indicates anagramming the letters.
'sailor' anagrammed gives 'rosial'.
'a'+'rosial'='arosial'
'mb' going into 'arosial' is 'AMBROSIAL'.
(Other definitions for ambrosial that I've seen before include "Divine" , "Heavenly" , "Like special food" , "delicious" , "Delightful" .)
