Wife going sick, complaining (7)

I believe the answer is:

wailing

'complaining' is the definition.

'wife going sick' is the wordplay.
'wife' becomes 'w'.
'going sick' becomes 'ailing'.
'w'+'ailing'='WAILING'

(Other definitions for wailing that I've seen before include "Jerusalem site sacred to Jews for prayer and lamentation" , "Greeting" .)

I've seen this clue in The Guardian.
