The term "shares" originates from the Old English word "scear," which denotes the cutting blade of a plow. In the context of Katharine Lee Bates' poem "The Fellowship," "burning shares" evokes the image of martyrdom and the intense suffering endured by those who are dedicated to a cause. This usage highlights the theme of sacrifice and the shared experiences of pain among artists and those who strive for a greater understanding of humanity.

The term "shares" is not commonly used in contemporary language, making it an archaic term that may require explanation for modern readers. Related terms include "plowshare," which specifically refers to the part of a plow that turns the soil. When analyzing poetry, it’s important to consider the historical context of language, as many archaic terms carry deeper meanings that enrich the text. The use of "shares" in Bates' poem can be contrasted with more modern expressions of suffering, which may not carry the same agricultural connotation. Etymologically, "shares" is linked to agricultural practices, emphasizing the connection between labor, sacrifice, and artistic creation.
