Woman with enfants (4)
I believe the answer is:
mere
'woman with enfants' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mere that I've seen before include "Lake; Wiltshire town" , "Lake (poetic); Maori war club" , "Nothing more than a small pond" , "Lake in Cumbria" , "Just an English lake" .)
