Wife and I and daughter initially earned extra (4)
I believe the answer is:
wide
'extra' is the definition.
(cricket term)
'wife and i and daughter initially earned' is the wordplay.
'wife' becomes 'w' (abbreviation).
'and' means one lot of letters go next to another.
'and' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'initially' suggests taking the first letters.
The first letter of 'earned' is 'e'.
'w'+'i'+'d'+'e'='WIDE'
(Other definitions for wide that I've seen before include "Broad - extra" , "Far from the target" , "Unplayable ball (cricket)" , "(At cricket) an extra" , "shrewd and shifty" .)
