Order soldiers away from alcohol inside? That's not right (7)
I believe the answer is:
oblique
'order' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for oblique that I've seen before include "Indirect - devious" , "Slanted" , "Angled" , "Slanting, or expressed indirectly" , "Slanting, indirect" .)
