It's actually only one word (as the 'rules' of the puzzle dictate), but the two characters preceding the word in the clue could be viewed as a helpful indication of where that particular meaning of the entry originated.
...as I noted before, the constraints associated with a single word definition mean that sometimes that definition is a little 'loose' and indications of locale, obsoleteness etc must by necessity be omitted (eg for the entry at 12ac).
