Cautious when getting head down and twisted to one side (4)
I believe the answer is:
awry
'twisted to one side' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for awry that I've seen before include "Wrong, amiss" , "Out of kilter" , "deviant" , "out of uniform?" , "Haywire" .)
