Deciding to put off digging (11)
I believe the answer is:
determining
'deciding' is the definition.
(I know that deciding can be written as determining)
'put off digging' is the wordplay.
'put off' becomes 'deter' (both can mean to discourage).
'digging' becomes 'mining' (I can't explain this - if you can you should give a lot more credence to this answer).
'deter'+'mining'='DETERMINING'
'to' is the link.
Can you help me to learn more?
(Other definitions for determining that I've seen before include "Firmly deciding" , "Making a decision" .)
