The vocation of the visitor? (7)
I believe the answer is:
calling
'the vocation' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for calling that I've seen before include "Ringing" , "visiting" , "Running a bingo game" , "Predicting the outcome" , "Vocation or profession" .)
