Inappropriate of problem daughter to purchase magazine (3-5)
I believe the answer is:
ill timed
'inappropriate' is the definition.
(synonyms)
'problem daughter to purchase magazine' is the wordplay.
'problem' becomes 'ill' (I've seen this in other clues).
'daughter' becomes 'd' (genealogical abbreviation).
'to purchase' is an insertion indicator.
'magazine' becomes 'time' (US magazine).
'ill'+'d'='illd'
'illd' placed around 'time' is 'ILL-TIMED'.
'of' is the link.
(Other definitions for ill timed that I've seen before include "at the wrong moment" , "Inappropriate" .)
