Veil turned, perhaps, hiding mother and kid’s faces (7)
I believe the answer is:
yashmak
'veil' is the definition.
(yashmak is a kind of veil)
'turned perhaps hiding mother and kid's faces' is the wordplay.
'turned' shows that the letters should be reversed in order.
'perhaps' becomes 'say' (both can mean 'for example').
'faces' suggests taking the first letters (I've seen 'face' mean this).
The initial letters of 'hiding mother and kids' is 'hmak'.
'say' reversed gives 'yas'.
'yas'+'hmak'='YASHMAK'
(Other definitions for yashmak that I've seen before include "Face covering" , "Veil worn by Muslim women in some countries" , "Veil worn by Muslim women to cover face" , "Eastern veil" , "Face-veil worn by Muslim women" .)
