Gear up for work in City (6)
I believe the answer is:
prague
'city' is the definition.
(Prague is an example)
'gear up for work' is the wordplay.
'for work' indicates an anagram (letters worked into a new form).
'gear'+'up'='gearup'
'gearup' is an anagram of 'PRAGUE'.
'in' is the link.
(Other definitions for prague that I've seen before include "Rather quiet" , "European capital" , "Czech Republic's capital" , "Capital city of Czech Republic" , "Gear up for this European city" .)
