Final answer:
The word 'eavesdrop' is used to imply a secretive and intentional act of listening to confidential conversations. It reflects the author's choice of language to enhance the sense of clandestine activities and can be part of the author's larger purpose to meet or challenge rhetorical norms.
Step-by-step explanation:
The use of the word eavesdrop suggests an intention to listen covertly to confidential information. The author may have chosen this word to convey a sense of secrecy and the potential for gathering intelligence without the speaker's awareness. This choice of language might indicate that the characters are not supposed to be overhearing the conversation and are doing so with a specific purpose in mind. When studying historical texts or analyzing an author's intent, it is important to consider their origin and the possibility of cultural biases, as they can influence the interpretation and understanding of a text (John's emphasis on the origin of texts). The text might also aim to meet or challenge conventional expectations in rhetorically effective ways, which is a critical aspect of analyzing an author's purpose whether to persuade, inform, entertain, describe, or explain.
