 This command can be seen as a generalization of {\tt Fixpoint}.  It is actually
 a wrapper for several ways of defining a function \emph{and other useful
   related objects}, namely: an induction principle that reflects the
-recursive structure of the function (see \ref{FunInduction}), and its
+recursive structure of the function (see \ref{FunInduction}) and its
 fixpoint equality.
  The meaning of this
 declaration is to define a function {\it ident}, similarly to {\tt
   Fixpoint}. Like in {\tt Fixpoint}, the decreasing argument must be
-given (unless the function is not recursive), but it must not
-necessary be \emph{structurally} decreasing. The point of the {\tt
+given (unless the function is not recursive), but it might not
+necessarily be \emph{structurally} decreasing. The point of the {\tt
   \{\}} annotation is to name the decreasing argument \emph{and} to
 describe which kind of decreasing criteria must be used to ensure
 termination of recursive calls.
