A deviation, swinging round in different direction (4)
I believe the answer is:
away
'a deviation swinging round in different direction' is the definition.
I can't judge whether this definition defines the answer.
'a deviation swinging round' is the wordplay.
'deviation' becomes 'yaw' (deviation of an aircraft around a vertical axis).
'swinging round' shows that the letters should be reversed in order.
'yaw' written backwards gives 'way'.
'a'+'way'='AWAY'
Can you help me to learn more?
(Other definitions for away that I've seen before include "Elsewhere" , "On holiday" , "constantly" , "SECOND PART OF 4 DOWN" , "At a distance; match" .)
