Would you say "President Biden" does not involve an apposition? Is that a "circular claim?"
Here is an example given of apposition:
“the first US president, George Washington”
”the current acting US President, Joseph Biden”
would be the similar apposition.
Your ignorance on the mandatory apposition claim is really a terrible blunder on any GSR verse, again highlighting your weakness in English and logic.
Why not answer the question.
What was “tacked on afterward”.
Or was that yet another blunder?
