What term do the animals on the farm use to address each other?

The animals on the farm use the term "Comrades" to address each other, which reflects the ideals of unity and equality among them. This choice is significant as it embodies the principles of the Animalist ideology established by Old Major, which encourages solidarity amongst the animals against their human oppressors. The term "comrade" invokes a sense of shared purpose and collective identity, emphasizing their common struggle for freedom and fair treatment. This usage is particularly aligned with revolutionary rhetoric, reinforcing the themes of camaraderie and collective action that are central to the narrative of "Animal Farm." It distinguishes their relationships from more personal or familial terms, highlighting the political and social motivations behind their interactions.
