Final answer:
Phillis Wheatley's phrase 'Egyptian gloom' in her poetry has negative connotations, indicating darkness and despair associated with slavery, and subtly critiques the institution while communicating effectively with her audience.
Step-by-step explanation:
In Phillis Wheatley's poetry, one example of a phrase with negative connotations is "Egyptian gloom". This phrase from her work carries a negative connotation because 'gloom' suggests darkness and despair, which can reflect the grim reality of slavery. Furthermore, during Wheatley's time, 'Egyptian' could be associated with Biblical enslavement, thus the phrase "Egyptian gloom" deepens the critique of slavery. By using such language, Wheatley underscores the sorrow and hardship associated with slavery while subtly critiquing it. This usage is complex because it also preserves Wheatley's ability to communicate with, and perhaps gain the sympathy of, her largely white audience by using language and Biblical references they were familiar with. Her strategic choice in diction allows Wheatley to use her platform to point towards the injustices of slavery while still addressing the sensitivities of her readership.
