... and avoid a western city (5)
I believe the answer is:
dodge
'western city' is the definition.
(Dodge City, Kansas, Wild West frontier town)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for dodge that I've seen before include "Avoid with subterfuge" , "Move quickly out of the way of" , "Take evasive action" , "bypass" , "A quick evasive movement" .)
