The traveller has to wander and be censorious (7)
I believe the answer is:
reprove
'be censorious' is the definition.
I can't judge whether this definition defines the answer.
'the traveller has to wander' is the wordplay.
'the traveller' becomes 'rep' (travel company worker).
'has' means one lot of letters go next to another.
'to wander' becomes 'rove' ('rove' can be a synonym of 'wander').
'rep'+'rove'='REPROVE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for reprove that I've seen before include "carpet" , "Scold" , "Admonish" , "Rebuke, censure" , "tick off" .)
