Son trapped by loveless marriage unlikely to delete ... (9)
I believe the answer is:
uninstall
'delete' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'son trapped by loveless marriage unlikely' is the wordplay.
I cannot really understand how this works, but
'son' could be 's' and 's' is found within the answer.
'unlikely' could be 'tall' (I've seen this before) and 'tall' is found within the answer.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for uninstall that I've seen before include "Get rid" , "Remove an app from a computer" .)
