A letter to the editor (sometimes abbreviated LTTE or LTE) is a letter sent to a publication about issues of concern to its readers. Usually, letters are intended for publication. Usually, letters to the editor are associated with newspapers and newsmagazines. However, they are sometimes sent to other periodicals (such as entertainment and technical magazines), and radio and television stations. In the latter instance, letters are sometimes read on the air (usually, on a news broadcast or on talk radio).
