Foreign yeoman started from large town with bullock, heading east to make return (6)
I believe the answer is:
exotic
'foreign' is the definition.
(similar in meaning)
'bullock heading east to make return' is the wordplay.
'bullock' becomes 'ox'.
'heading east' becomes 'e' (abbreviation).
'to' says to put letters next to each other (I've seen this in other clues).
'make' becomes 'cit' (I can't explain this - if you can you should believe this answer much more).
'return' says the letters should be written backwards.
'ox'+'e'='oxe'
'oxe' put after 'cit' is 'citoxe'.
'citoxe' back-to-front is 'EXOTIC'.
'yeoman started from large town with' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for exotic that I've seen before include "Unusual and interesting" , "Strikingly strange or unusual" , "Foreign-looking" , "Interestingly different or strange" , "Having a strange beauty" .)
