Being an employer helps to make you single-minded (5)
I believe the answer is:
using
'being an employer' is the definition.
The answer and definition can be both to do with social activities as well as being present participle verbs.
Perhaps there's a link between them I don't understand?
'helps to make you single-minded' is the wordplay.
'helps to make' indicates a hidden word (I've seen 'helping to make' mean this).
'USING' is hidden in the letters of 'you single minded'.
Can you help me to learn more?
(Other definitions for using that I've seen before include "practice" , "having recourse to" , "Exploiting for one's own advantage" , "Exercising" , "Putting into service" .)
