+= Keywords
+
+Keywords are words that have a special meaning in Cypher.
+
+The keywords are not recommended to be used as identifiers in the following contexts:
+
+* Variables
+* Labels
+* Relationship types
+
+If a snippet of Cypher can validly be a keyword as well as an unquoted identifier, it is always interpreted as a keyword.
+
+For instance in the following, `true` could be the variable `true` or the Boolean literal value `true`. Since `true` is a keyword, the query returns a single Boolean `true` value.

+[source, cypher, role=test-result-skip]

+
+If any keyword is quoted in backticks (```), such as `++`true`++`, it is always interpreted as an identifier in the given context.
