Some mother almost seen as a goddess (4)
I believe the answer is:
hera
'a goddess' is the definition.
(thesaurus)
'some mother almost seen' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'HERA' is hidden in the letters of 'mother almost seen'.
'as' is the link.
(Other definitions for hera that I've seen before include "Regularly-deceived wife" , "Queen whose Roman counterpart was Juno" , "Greek equivalent of Juno" , "Consort of Zeus" , "Sister and wife of 18" .)
