Chap fencing in quiet wood (5)
I believe the answer is:
maple
'wood' is the definition.
(I know that maple is a type of wood)
'chap fencing in quiet' is the wordplay.
'chap' becomes 'male' (chap can mean a man).
'fencing' is an insertion indicator (to fence can mean to contain or put a limit round).
'in quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet. I am not sure about the 'in' bit.).
'male' enclosing 'p' is 'MAPLE'.
Can you help me to learn more?
(Other definitions for maple that I've seen before include "Tree with syrupy sap" , "Tree of Acer genus" , "Emblematic tree of Canada" , "Tree of the sycamore family" , "Source of syrup" .)
