Woman's meeting daughter in crowd (4)
I believe the answer is:
herd
'crowd' is the definition.
(herding is a kind of crowding)
'woman's meeting daughter' is the wordplay.
'woman' becomes 'her' (pronoun for a woman).
'meeting' says to put letters next to each other.
'daughter' becomes 'd'.
'her'+'d'='HERD'
'in' is the link.
(Other definitions for herd that I've seen before include "Host" , "Group of cows, elephants etc" , "Drive" , "cattle together" , "Collection of swine" .)
