In Chile, a perfect spring (4)
I believe the answer is:
leap
'spring' is the definition.
(both can mean to jump)
'in chile a perfect' is the wordplay.
'in' says the answer is hidden in the clue.
'LEAP' can be found hidden inside 'chile a perfect'.
(Other definitions for leap that I've seen before include "Spring suddenly" , "Sudden bound" , "vault" , "Jump; type of year" , "Jump suddenly" .)
