Relative's hurting a lad, we suspect (8-2-3)
I believe the answer is:
daughter-in-law
'relative's' is the definition.
(I've seen this before)
'hurting a lad we suspect' is the wordplay.
'suspect' indicates anagramming the letters (a suspicious or unusual spelling).
'hurting'+'a'+'lad'+'we'='hurtingaladwe'
'hurtingaladwe' with letters rearranged gives 'DAUGHTER-IN-LAW'.
(Other definitions for daughter-in-law that I've seen before include "Female relative by marriage" , "One's son's wife" , "Woman married to one's child" .)
