Some Glaswegian gusto in part of Scotland (5)
I believe the answer is:
angus
'part of scotland' is the definition.
(I know that Angus is part of Scotland)
'some glaswegian gusto in' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'ANGUS' can be found hidden inside 'glaswegian gusto in'.
(Other definitions for angus that I've seen before include "man" , "Former Scottish county" , "Scots man's name" , "Aberdeen . . . . ., breed of cattle" , "A snug breed from Aberdeen" .)
