Wife I left — and daughter — will be angry (4)
I believe the answer is:
wild
'angry' is the definition.
('wild' can be a synonym of 'angry')
'wife i left and daughter' is the wordplay.
'wife' becomes 'w'.
'left' becomes 'l' (common abbreviation).
'and' means one lot of letters go next to another.
'daughter' becomes 'd'.
'w'+'i'+'l'+'d'='WILD'
'will be' is the link.
(Other definitions for wild that I've seen before include "Fierce" , "Feral, untamed" , "Not domesticated" , "Feral - crazy" , "unruly" .)
