   * arithmetic operator:  *, /, +, -
   * atomic data types:  Single valued types (e.g. int, float).
-  * comparitor:   boolean operations that test equality, inequality, or do another comparison (such as MATCHES).
+  * comparator:   boolean operations that test equality, inequality, or do another comparison (such as MATCHES).
   * complex data types:   Multi-valued types (e.g. bag).
   * datum:  A value, could be of complex or atomic type.
-  * expression operators:  Language constructs used in FILTER or FOREACH statements that evaluate expressions of data.  These include comparitors, arithmetic operators, user defined functions, and language provided functions.
