Explanation:
The question is about Sam Watson, a character from the novel "Their Eyes Were Watching God" by Zora Neale Hurston.
This novel is filled with vernacular language, as a part of the setting of the story.
Questioning means doubting a validity of something, demanding a proof, querying.
Sam Watson, in this particular situation, used the term "questionizin" as a synonim for "asking" ("Ah'm questionizin' you!")
Although both words have the same root (question) their meanings slightly differ, as shown, but in spite of that difference, Sam's sentence can be understood in a proper context.
Answer: Romeo is a Montague and Juliet is a Capulet. They are a part of two families that have a long-lasting feud against each other that seems like it will never end. Romeo and Juliet were not able to be together because of their families, but they still made it happen.
Can you be more specific with your question I don’t think we understand
