I almost stop probing firewood delivery arrangements (9)
I believe the answer is:
logistics
'delivery arrangements' is the definition.
(the industry of transporting goods)
'i almost stop probing firewood' is the wordplay.
I cannot really see how this works, but
'i' is within the answer.
'firewood' could be 'log' (log is a kind of firewood) and 'log' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for logistics that I've seen before include "Art of military movement and supply" , "Task of movement and supply of troops" , "organisation" .)
