Neat, no energy at all outside the province (5)
I believe the answer is:
natal
'province' is the definition.
(I know that Natal is a province)
'neat no energy at all outside the' is the wordplay.
'neat no energy' becomes 'na' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'at' says to put letters next to each other.
'outside' means to remove the middle letters.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'all' with its middle removed is 'al'.
'al' put after 't' is 'tal'.
'na'+'tal'='NATAL'
Can you help me to learn more?
(Other definitions for natal that I've seen before include "Colony once" , "of births" , "dealing with delivery" , "former SA province" , "South African region" .)
