 The SUM (permit Supervisor User Memory access) bit modifies the privilege with
-which S-mode loads, stores, and instruction fetches access virtual memory.
+which S-mode loads and stores access virtual memory.
 When SUM=0, S-mode memory accesses to pages that are accessible by U-mode (U=1
 in Figure~\ref{sv32pte}) will fault.  When SUM=1, these accesses are
 permitted.  SUM has no effect when page-based virtual memory is not in effect.
