+A simple example of a statement
+
+  Charles Darwin was born in Shrewsbury
+
+A statement describes some truth about something
+
+Deconstructing a statement
+
+- _Subject_: The main actor on the statement (`Charles` `Darwin`)
+- _Predicate_: The verb qualifying the statement (`born` `in`)
+- _Object_: What is being predicated (`Shrewsbury`)
+
+There are two entities (`Charles` `Darwin` and `Shrewsbury`) linked by a verb
+
+* Another statement
+
+This is also a simple statement, but with a twist
+
+  Nikola Tesla knew Charles Darwin was born in Shrewsbury
+
+A possible way of desconstructing the statement
+
+- _Subject_: `Nikola` `Tesla`
+- _Predicate_: `knew`
+- _Object_: `Charles` `Darwin` `was` `born` `in` `Shrewsbury`
+
+You can have entities in a statement, but you can also have other statements
+
+The above example links an entity with another statement
+
+* One last statement
+
+One final statement
+
+  Shrewsbury population 6,000
+
+This statement is build using
+
+- _Subject_: (`Shrewsbury`)
+- _Predicate_: A property (`population`)
+- _Object_: The value of the property (`6,000`)
+
+A statement may not define a relation, but describe a _property_
+
+The object of properties are primitive data types. Some examples
+
+- _Text_
+- _Numbers_
+- `...`
