Grazing animals on accessible land sounded appropriate (10)

I believe the answer is:
commandeer
'appropriate' is the definition.
(I've seen this in another clue)
'grazing animals on accessible land sounded' is the wordplay.
I cannot really understand how this works, but
'animals' could be 'deer' (type of animals) and 'deer' is located in the answer.
'land' could be 'man' (Man is an example) and 'man' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for commandeer that I've seen before include "Take control of for military purposes" , "Appropriate" , "Take control of for military use" , "Take by force" , "Confiscate" .)
