+Here, the group verbP denotes two sets of non-terminals with the corresponding actions that are substituted for the expression group(verbP) on the RHS of the clause non-terminal.

+Rule is of level 3. When we turn the grammar level to at least 3, we allow adjective groups to form a separate intersegment.
+
+''head()'' and ''depends()'': allow to express the dependency links between rule items. For example depends(A,B,C) means that B and C depends on A.
+
+
+== Second grammar form ==
+As we have mentioned earlier, several pre-defined grammatical tests and procedures are used in the description of context actions associated with each grammatical rule of the system. 
+
+The pruning actions include:
+ • grammatical case test for particular words and noun groups
+ • agreement test of case in prepositional construction
+ • agreement test of number and gender for relative pronouns
+ • agreement test of case, number and gender for noun groups
+ • type checking of logical constructions
+
+'''Example:'''
+
+{{{
+np -> adj_group np
+      rule_schema($@, "lwtx(awtx(#1) and awtx(#2))")
+      rule_schema($@, "lwtx([[awt(#1),#2],x])")
+}}}
+
+The rule schema action presents a prescription for building a logical construction out of the sub-constructions from the right hand side.
+''propagate_all'' and ''agree_*_and_propagate'': compute and propagate all relevant grammatical information from the selected non-terminals on the right hand side to the one on the left hand side of the rule.
+
+
+== The Expanded Grammar Form (G3) ==
+
+Transform G2 form with the contextual actions into the rules.
