Some precedence given to garden (4)
I believe the answer is:
eden
'to garden' is the definition.
(Garden of Eden in the Bible)
'some precedence given' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'EDEN' is hidden in the letters of 'precedence given'.
(Other definitions for eden that I've seen before include "The - - Project, Cornwall" , "Anthony ---, PM 1955" , "(Biblical) paradise" , "Adam and Eve's first home" , "Someone once seen in Number Ten's" .)
