-**                       and nonterminals.  "int" is used otherwise.
-**    YYNOCODE           is a number of type YYCODETYPE which corresponds
-**                       to no legal terminal or nonterminal number.  This

+**    YYCODETYPE         is the data type used to store the integer codes
+**                       that represent terminal and non-terminal symbols.
+**                       "unsigned char" is used if there are fewer than

+**    YYNOCODE           is a number of type YYCODETYPE that is not used for
+**                       any terminal or nonterminal symbol.
 **    YYFALLBACK         If defined, this indicates that one or more tokens
-**                       have fall-back values which should be used if the
-**                       original value of the token will not parse.
-**    YYACTIONTYPE       is the data type used for storing terminal
-**                       and nonterminal numbers.  "unsigned char" is
-**                       used if there are fewer than 250 rules and
-**                       states combined.  "int" is used otherwise.
-**    grn_expr_parserTOKENTYPE     is the data type used for minor tokens given 
-**                       directly to the parser from the tokenizer.
-**    YYMINORTYPE        is the data type used for all minor tokens.
+**                       (also known as: "terminal symbols") have fall-back
+**                       values which should be used if the original symbol
+**                       would not parse.  This permits keywords to sometimes
+**                       be used as identifiers, for example.
+**    YYACTIONTYPE       is the data type used for "action codes" - numbers
+**                       that indicate what to do in response to the next
+**                       token.
+**    grn_expr_parserTOKENTYPE     is the data type used for minor type for terminal
+**                       symbols.  Background: A "minor type" is a semantic
+**                       value associated with a terminal or non-terminal
+**                       symbols.  For example, for an "ID" terminal symbol,
+**                       the minor type might be the name of the identifier.
+**                       Each non-terminal can have a different minor type.
+**                       Terminal symbols all have the same minor type, though.
+**                       This macros defines the minor type for terminal 
+**                       symbols.
+**    YYMINORTYPE        is the data type used for all minor types.
 **                       This is typically a union of many types, one of
 **                       which is grn_expr_parserTOKENTYPE.  The entry in the union
-**                       for base tokens is called "yy0".
+**                       for terminal symbols is called "yy0".
 **    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
 **                       zero the stack is dynamically sized using realloc()
 **    grn_expr_parserARG_SDECL     A static variable declaration for the %extra_argument
