Enjoy run, hour covering exotic isle (6)
I believe the answer is:
relish
'enjoy' is the definition.
('relish' can be a synonym of 'enjoy')
'run hour covering exotic isle' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'hour' becomes 'h'.
'covering' indicates putting letters inside.
'exotic' indicates anagramming the letters.
'r'+'h'='rh'
'isle' with letters rearranged gives 'elis'.
'rh' going around 'elis' is 'RELISH'.
(Other definitions for relish that I've seen before include "Savour; chutney" , "Gusto" , "Salsa-like sauce" , "Taste like sauce" , "Enjoy; piquant sauce" .)
