A letter is a written message conveyed from one person to another through a medium. Something epistolary means that it is a form of letter writing. The term usually excludes written material intended to be read in its original form by large numbers of people, such as newspapers and placards, although even these may include material in the form of an "open letter". The typical form of a letter for many centuries, and the archetypal concept even today, is a sheet of paper that is sent to a correspondent through a postal system. A letter can be formal or informal, depending on its audience and purpose. Besides being a means of communication and a store of information, letter writing has played a role in the reproduction of writing as an art throughout history. Letters have been sent since antiquity and are mentioned in the Iliad. Historians Herodotus and Thucydides mention and use letters in their writings.
Ms. or Ms is an English-language honorific used with the last name or full name of a woman, intended as a default form of address for women regardless of marital status. Like Miss and Mrs., the term Ms. has its origins in the female English title once used for all women, Mistress. It originated in the 17th century and was revived into mainstream usage in the 20th century.
Sir is a formal honorific address in English for men, derived from Sire in the High Middle Ages. Both are derived from the old French "Sieur" (Lord), brought to England by the French-speaking Normans, and which now exist in French only as part of "Monsieur", with the equivalent "My Lord" in English.
An email address identifies an email box to which messages are delivered. While early messaging systems used a variety of formats for addressing, today, email addresses follow a set of specific rules originally standardized by the Internet Engineering Task Force (IETF) in the 1980s, and updated by RFC 5322 and 6854. The term email address in this article refers to just the addr-spec in Section 3.4 of RFC 5322. The RFC defines address more broadly as either a mailbox or group. A mailbox value can be either a name-addr, which contains a display-name and addr-spec, or the more common addr-spec alone.
Esquire is usually a courtesy title. In the United Kingdom, esquire historically was a title of respect accorded to men of higher social rank, particularly members of the landed gentry above the rank of gentleman and below the rank of knight. Some sources cite that the title was bestowed on "candidates for knighthood in England", and even used with respect to other dignitaries, such as justices of the peace, sheriffs, and sergeants.
Dead letter mail or undeliverable mail is mail that cannot be delivered to the addressee or returned to the sender. This is usually due to lack of compliance with postal regulations, an incomplete address and return address, or the inability to forward the mail when both correspondents move before the letter can be delivered. Largely based on the British model that emerged in the late eighteenth century, many countries developed similar systems for processing undeliverable mail.
In Modern English, the word "you" is the second-person pronoun. It is grammatically plural, and was historically used only for the dative case, but in most modern dialects is used for all cases and numbers.
Ciao is an informal salutation in the Italian language that is used for both "hello" and "goodbye".
Poste restante, also known as general delivery in North American English, is a service where the post office holds the mail until the recipient calls for it. It is a common destination for mail for people who are visiting a particular location and have no need, or no way, of having mail delivered directly to their place of residence at that time.
The "Dear Boss" letter was a message allegedly written by the notorious unidentified Victorian serial killer known as Jack the Ripper. Addressed to the Central News Agency of London and dated 25 September 1888, the letter was postmarked and received by the Central News Agency on 27 September. The letter itself was forwarded to Scotland Yard on 29 September.
A business letter is a letter from one company to another, or such organizations and their customers, clients, or other external parties. The overall style of letter depends on the relationship between the parties concerned. Business letters can have many types of content, for example to request direct information or action from another party, to order supplies from a supplier, to point out a mistake by the letter's recipient, to reply directly to a request, to apologize for a wrong, or to convey goodwill. A business letter is sometimes useful because it produces a permanent written record, and may be taken more seriously by the recipient than other forms of communication. It is written in formal language.
Diplomatic correspondence is correspondence between one state and another and is usually of a formal character. It follows several widely observed customs and styles in composition, substance, presentation, and delivery and can generally be categorized into letters and notes.
God bless you is a common English phrase generally used to wish a person blessings in various situations, especially to "will the good of another person", as a response to a sneeze, and also, when parting or writing a valediction. The phrase has been used in the Hebrew Bible by Jews, and by Christians, since the time of the early Church as a benediction, as well as a means of bidding a person Godspeed. Many clergy, when blessing their congregants individually or as a group, use the phrase "God bless you".
A salutation is a greeting used in a letter or other communication. Salutations can be formal or informal. The most common form of salutation in an English letter includes the recipient's given name or title. For each style of salutation there is an accompanying style of complimentary close, known as valediction. Examples of non-written salutations are bowing, waving, or even addressing somebody by their name. A salutation can be interpreted as a form of a signal in which the receiver of the salutation is being acknowledged, respected or thanked. Another simple but very common example of a salutation is a military salute. By saluting another rank, that person is signalling or showing his or her acknowledgement of the importance or significance of that person and his or her rank. Some greetings are considered vulgar, others "rude" and others "polite".
A directory harvest attack (DHA) is a technique used by spammers in an attempt to find valid/existent e-mail addresses at a domain by using brute force. The attack is usually carried out by way of a standard dictionary attack, where valid e-mail addresses are found by brute force guessing valid e-mail addresses at a domain using different permutations of common usernames. These attacks are more effective for finding e-mail addresses of companies since they are likely to have a standard format for official e-mail aliases.
Have a nice day is a commonly spoken expression used to conclude a conversation, or end a message by hoping the person to whom it is addressed experiences a pleasant day. It is often uttered by service employees to customers at the end of a transaction, particularly in Israel and the United States. According to some journalists and scholars, its repetitious and dutiful usage has resulted in the phrase developing secondary cultural connotations of, variously, impersonality, lack of interest, passive–aggressive behavior, sarcasm or as a definitive way to put an end to a conversation and dismiss the other party.
A round-robin letter or Christmas letter is a letter, typically included with a Christmas card and sent to multiple recipients at the end of the year, in which the writer describes the year's events for themselves and/or their family.
"Your Obedient Servant" is the twentieth song from Act 2 of the musical Hamilton, based on the life of Alexander Hamilton, which premiered on Broadway in 2015.
