Tan switches from a formal to a narrative structure in this essay because it reflects her insights on language. The author describes how her mother's developing English has effected her realizations about communication and how it affects her life. Thus Tan used narration as a tool to best express her reflections. This descriptive style helped readers understand the author's experiences and relate to them. It guides readers to visualize what immigrants go through when they try to communicate. The narrative essay is an effective form because it provides scenarios that can make readers see the author's main point of view. It also gives readers a richer experience when understanding the author's message.
