      "This C library provides semi-portable access to hardware-provided atomic
-memory update operations on a number architectures.  These might allow you to
+memory update operations on a number of architectures.  These might allow you to
 write code that does more interesting things in signal handlers, write
 lock-free code, experiment with thread programming paradigms, etc.")
