This document provides guidance on writing a formal application or letter of request. It notes that applications are shorter, more precise and focus on the summarized purpose, while letters can be formal or informal. The document then outlines the typical layout of an application, including addressing it to a specific person by their designation, using a respectful salutation, stating the direct purpose or problem concisely in the body, signaling the end by thanking the reader in advance, and closing with yours sincerely/faithfully and the applicant's name and date.
