Somehow get loner to sign up (5)
I believe the answer is:
enrol
'sign up' is the definition.
(I've seen this before)
'somehow get loner' is the wordplay.
'loner' can be anagrammed to 'ENROL'.
However, I am not sure how this is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for enrol that I've seen before include "Enlist" , "register for classes" , "Join up, sing on" , "Join up, sign on" , "Enter" .)
