Frenzied Scot goes round province (5)
I believe the answer is:
manic
'frenzied' is the definition.
(I've seen this before)
'scot goes round province' is the wordplay.
'scot' becomes 'mac' (many Scottish surnames begin with Mac).
'goes round' means one lot of letters goes inside another.
'province' becomes 'ni' (I've seen this in other clues).
'mac' going around 'ni' is 'MANIC'.
(Other definitions for manic that I've seen before include "hyperactive?" , "Frenzied" , "Obsessive" , "Showing wild energy" , "Unnaturally excited" .)
