In the poem "Harriet Tubman" by Eloise Greenfield, the author makes use of double negative in several verses, meaning that two forms of negation are used within the same sentence. This is a non-standard use of the english language in a formal format; it is used by the author for the following reasons:
1. The author uses various forms of negation within a sentence in order to emphasize the means of the character, Harriet Tubman, to describe her personality and desires.
2. The colloquial dialect in the poem ensures (assuming the author pretends to address an audience from an early age), that anyone who can relate to the poem's protagonist, Harriet Tubman, is able to receive the message in a clear way.
3. The author assumes the character, Harriet Tubman, would have commmunicated the same way as written in the poem.
