Tourist on vacation eats a cold delicacy (4)
I believe the answer is:
tact
'delicacy' is the definition.
(thesaurus)
'tourist on vacation eats a cold' is the wordplay.
'on vacation' says to hollow out the word (remove centre letters).
'eats' is an insertion indicator.
'a cold' becomes 'ac' (I've seen this in other clues).
'tourist' with its centre removed is 'tt'.
'tt' going around 'ac' is 'TACT'.
(Other definitions for tact that I've seen before include "Diplomatic sensitivity" , "Understanding" , "Fine perception" , "Sensitivity (in dealing with others)" , "Consideration in dealing with others" .)
