Hi. From the context of your question, I believe you are referring to Momma or Mrs Flowers from the book "I Know Why the Caged Bird Sings" written by Maya Angelou. Accordingly, I hope the answer below will help you.
Answer and Explanation:
"I Know Why the Caged Bird Sings" is a biographical work by Maya Angelou, where she presents experiences of her life as a black woman. In this work we are introduced to Momma, Maya's grandmother. Momma is a very strong woman, who is aware of her worth and who does not allow her or her family to be devalued. For this reason, she makes Maya and her brother study hard, attend church, and become very intelligent and educated adults. Despite this, Momma cannot face the prejudice that she suffers, because despite all the strength she has, she is very afraid of the consequences that prejudice can promote. In this case, we can say that even with all the strength she has, Momma is still oppressed by prejudice and racism.
