Educated woman unwrapped small packages for husband and wife (7)
I believe the answer is:
marital
'for husband and wife' is the definition.
'educated woman unwrapped small packages' is the wordplay.
'educated woman' becomes 'rita' (ref to play and film Educating Rita**).
'unwrapped' means to look at the middle letters (the letters which wrap the word are removed).
'packages' indicates putting letters inside.
The central letters of 'small' are 'mal'.
'rita' placed inside 'mal' is 'MARITAL'.
(Other definitions for marital that I've seen before include "Sort of union" , "This type of bliss" , "Of a wedding" , "related to union" , "to do with life together" .)
