Answer :
Minor characters are ones that support the story or conflict of the main character. What is it about Mrs. English that adds to the story or the conflict? Is perhaps a student or child or neighbor the main character in which Mrs. English causes distress or problems for the main character? For example, in the movie The Little Mermaid, Ursula is a minor character as she causes Ariel to have problems without Prince Eric, lose her voice, almost lose her family, etc.
