Step-by-step explanation:
The catchphrase repeated all over the speech is "ain't I a woman?" This phrase serves as a rhetorical device used by Sojourner Truth to emphasize her point about the equal treatment of women.
By repeating the phrase throughout her speech, Truth is drawing attention to the fact that despite being a woman, she is no less deserving of respect and equal treatment than any man. She is essentially challenging the prevailing attitudes and beliefs of her time that women were inferior to men and did not deserve the same rights and opportunities.
The repetition of the phrase also serves to create a sense of solidarity among women and to inspire them to fight for their rights. By asserting her own worth and value as a woman, Truth is encouraging other women to do the same and to demand equal treatment and rights.
Overall, the repetition of the phrase "ain't I a woman?" is a powerful rhetorical device used by Sojourner Truth to challenge gender inequality and to inspire others to fight for women's rights.
