Dear little couple supporting society (7)
I believe the answer is:
sweetie
'dear' is the definition.
(both are terms of endearment)
'little couple supporting society' is the wordplay.
I cannot quite see how this works, but
'little' could be 'wee' (similar in meaning) and 'wee' is located in the answer.
'couple' could be 'tie' (I've seen this in another clue) and 'tie' is present in the answer.
'society' could be 's' (common abbreviation in names of organisations) and 's' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
(Other definitions for sweetie that I've seen before include "Maybe boyfriend" , "treasure?" , "honey" , "Term of endearment" , "Love" .)
