Hell, following start of script in sunglasses (6)
I believe the answer is:
shades
'sunglasses' is the definition.
(synonyms)
'hell following start of script' is the wordplay.
'hell' becomes 'hades' (synonyms).
'following' means one lot of letters go next to another.
'start of script' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'hades' after 's' is 'SHADES'.
'in' is the link.
Can you help me to learn more?
(Other definitions for shades that I've seen before include "Sunglasses (informal)" , "Cool sunglasses or archaic ghosts" , "suspicions" , "Hues, colours" , "disguise, sometimes" .)
