I have to follow husband home (4)
I believe the answer is:
hive
'home' is the definition.
(I have seen 'home of queen' mean 'hive' so perhaps 'home' could also mean 'hive')
'i have to follow husband' is the wordplay.
'i have' becomes 'I've' (contraction of 'I have').
'to follow' says to put letters next to each other (some letters go after or follow others).
'husband' becomes 'h' (abbreviation).
'ive' put after 'h' is 'HIVE'.
(Other definitions for hive that I've seen before include "Skin rash from an insect home" , "home of queen" , "Bee box" , "A - of activity is a busy place" , "store" .)
