Where in Paris child gave shout of pain (4)
I believe the answer is:
ouch
'shout of pain' is the definition.
(I've seen this before)
'where in paris child' is the wordplay.
'where in paris' becomes 'ou'.
'child' becomes 'ch'.
'ou'+'ch'='OUCH'
'gave' is the link.
(Other definitions for ouch that I've seen before include "Pained exclamation" , "Pained expression" , "Cry of pain" , "brooch?" , "Pained cry" .)
