Take a look at part of Tuscany (4)
I believe the answer is:
scan
'take a look at' is the definition.
(scanning is a kind of taking a look at)
'part of tuscany' is the wordplay.
'part of' says the answer is hidden in the clue.
'SCAN' is hidden within 'tuscany'.
(Other definitions for scan that I've seen before include "Take a quick look" , "Survey - fit in metrically" , "Cast an eye over" , "Examine quickly" , "Examine data" .)
