The Ergativity Of Identifying Clauses

In identifying clauses, the Identified is the Medium of the Process, but the Identifier varies according to the direction of coding, functioning as

• the Range of a decoding clause, where it maps onto Value, but
• the Agent of an encoding clause, where it maps onto Token.

In other words,

1. decoding: Token/Identified/Medium and Value/Identifier/Range,
2. encoding: Token/Identifier/Agent and Value/Identified/Medium.

(The Identifier is the element that is most likely to be realised by tonic prominence — it is presented as New information.)
