Trim new garment dresses individual raising issue (6,6)
I believe the answer is:
single parent
'individual raising issue' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'trim new garment dresses' is the wordplay.
'trim new' becomes 'paren' (I can't explain this - if you can you should believe this answer much more).
'garment' becomes 'singlet' (singlet is a kind of garment).
'dresses' is an insertion indicator (some letters are contained by or dressed in others).
'paren' inserted into 'singlet' is 'SINGLE-PARENT'.
Can you help me to learn more?
(Other definitions for single parent that I've seen before include "family member who could do with more help?" , "Mother (with no partner)" , "caregiver going it alone - with 23a" , "Unmarried mother etc." .)
