Hey! How can I determine this clause structure in terms of sentence elements?
When Rachel arrived at her father`s table, the senator was on his cellphone talking loudly about one of his recent successes.
When Rachel arrived at her father`s table - adjunct of time
the senator - subject
was - predicator
on his cellphone talking loudly about one of his recent successes - ??? and what is the inner structure here, what is talking?
Thank you in advice
