Knave forced to travel (6)
I believe the answer is:
varlet
'knave' is the definition.
(synonyms)
'forced to travel' is the wordplay.
'travel' anagrams to 'VARLET'.
However, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for varlet that I've seen before include "Travel with old rascal" , "Travel (anag) - rascal (archaic)" , "Aged attendant" , "Travel around with old rogue" .)
