A cover letter is an introductory document typically sent alongside a résumé or curriculum vitae to provide a personal pitch to potential employers. Its primary function is to highlight an applicant’s specific qualifications, interest in a role, and professional personality beyond the bullet points of a standard application. These documents are generally categorized into application letters for known openings or inquiry letters for exploring potential opportunities. Effective versions are characterized by accurate grammar, a professional business format, and content specifically tailored to the target organization. While most common in the job market, they are also utilized for internship applications and various formal business transactions like loan requests or contract proposals.
