A.T. Robertson Commentary John 11:28

"And when she had said this, she went away, and called Mary her sister secretly, saying, The Teacher is her, and calleth thee." — John 11:28 (ASV)

Called Mary (εφωνησεν Μαριαμ). First aorist active indicative of φωνεω. Out of the house and away from the crowd.

Secretly (λαθρα). Old adverb from λαθρος (λανθανω). To tell her the glad news.

The Master (ο διδασκαλος). "The Teacher." So they loved to call him as he was (13:13). Is here (παρεστιν). "Is present."

Calleth thee (φωνε σε). This rouses Mary.
