“Dear Ijeawele” is an example of epistolary, meaning it was written in the form of a letter. This format testifies to the fact that this book is based on a real correspondence between the author and her close friend, Ijeawele. However, there is no reason why, in principle, it had to have been written in this format—it could have been written simply as a list of 15 principles aimed at parents. The fact that Adichie chose to keep the original format is a significant aspect of the book from voice to content, as well as how we interpret its suggestions.

The main advantage of the epistolary format is its ability to speak in a deeply intimate and personal voice, which places it in stark contrast to academic-style writing. The simple, clear prose gives the impression of a conversation more than it does a typical philosophical essay, and it’s far more accessible for that reason. The fact that it’s an informal piece of writing addressed to a friend means that, even when she writes about heavy subjects like oppression and discrimination, the tone remains positive and friendly. She manages to weave humor and light-hearted personal anecdotes between her more serious points.
