Sweet and innocent lady's seen in 3-D (8)
I believe the answer is:
cherubic
'sweet' is the definition.
(I know that sweet can be written as cherubic)
'innocent lady's seen in 3-d' is the wordplay.
'innocent lady' becomes 'her' (her refers to a woman. I am not sure about the 'innocent' bit.).
'seen in' is an insertion indicator.
'r-d' becomes 'cubic' (I've seen this in another clue).
'her' placed inside 'cubic' is 'CHERUBIC'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for cherubic that I've seen before include "Cute" , "Angelically innocent" , "Like a child" , "heavenly" , "Having a plump innocent face" .)
