Leaving home can be touching (6)
I believe the answer is:
moving
'be touching' is the definition.
(similar in meaning)
'leaving home' is the wordplay.
I cannot quite understand how this works, but
'home' could be 'in' ('he's home' can mean 'he's in') and 'in' is present in the answer.
This explanation may well be incorrect...
'can' is the link.
Can you help me to learn more?
(Other definitions for moving that I've seen before include "Arousing feelings of pity etc" , "Changing house, say" , "Going to other places" , "Not still" , "Mobile" .)
