Recess leads to pupils enjoying awesome spring break (4)
I believe the answer is:
apse
'recess' is the definition.
(apse is a kind of recess)
'leads to pupils enjoying awesome spring break' is the wordplay.
'leads to' indicates taking the first letters.
'break' indicates anagramming the letters.
The first letters of 'pupils enjoying awesome spring' is 'peas'.
'peas' with letters rearranged gives 'APSE'.
(Other definitions for apse that I've seen before include "Offshoot from the choir, nave or aisle in a church" , "Domed section of a church" , "space for altar" , "Church area" , "part of cathedral" .)
