Woman describes hail in the sky (6)
I believe the answer is:
heaven
'the sky' is the definition.
(thesaurus)
'woman describes hail' is the wordplay.
'woman' becomes 'hen' (**).
'describes' means one lot of letters goes inside another (describe can mean to form the outline of).
'hail' becomes 'ave' (I've seen this before).
'hen' placed around 'ave' is 'HEAVEN'.
'in' is the link.
(Other definitions for heaven that I've seen before include "Happy place" , "Abode of the gods" , "State of happiness" , "Place of supreme bliss" , "Abode of the blessed" .)
