Wild country? Public transport heading for home (4)
I believe the answer is:
bush
'wild country?' is the definition.
(I've seen this in another clue)
'public transport heading for home' is the wordplay.
'public transport' becomes 'bus' (bus is a kind of public transport).
'heading for' says to take the initial letters.
The first letter of 'home' is 'h'.
'bus'+'h'='BUSH'
(Other definitions for bush that I've seen before include "ex-president" , "Shrub; metal lining" , "part of shrubbery" , "41st US president, George" , "Shrub; wild vegetation" .)
