In this basic tree (taken from the Facebook page), Dylan is the antecedent and himself is the anaphor. Dylan and himself are coindexed as can be seen by the subscript indices. Dylan c-commands himself as illustrated by tree position.
An antecedent is a noun phrase that gives its meaning to another noun phrase.
An anaphor is a noun phrase that gets its meaning from another noun phrase in the clause.
Binding Principle A states that an anaphor must be bound in its binding domain.
The binding domain is, loosely stated, the clause in which the anaphor appears.
Binding is a relation between two phrases that involves c-command and coindexing.
More on c-command, coindexing and binding coming soon.
