About to change direction for the journey home (6)
I believe the answer is:
return
'home' is the definition.
(I know this)
'about to change direction' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'to change direction' becomes 'turn' (I've seen this before).
're'+'turn'='RETURN'
'for the journey' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for return that I've seen before include "Key on computer" , "election to parliament" , "Reappear" , "Homecoming" , "Proceeds" .)
