Note the & as the 27th character. The word ampersand is a corruption of the phrase "and per se & (and)", meaning "and intrinsically the word and (represented by the symbol &)".[2] Traditionally, when reciting the alphabet in English-speaking schools, any letter that could also be used as a word in itself ("A", "I", and, at one point, "O") was repeated with the Latin expression per se ("by itself").[3][4][5] This habit was useful in spelling where a word or syllable was repeated after spelling; e.g. "d, o, g—dog" would be clear but simply saying "a—a" would be confusing without the clarifying "per se" added. It was also common practice to add the "&" sign at the end of the alphabet as if it were the 27th letter, pronounced as the Latin et or later in English as and. As a result, the recitation of the alphabet would end in "X, Y, Z, and per se and". This last phrase was routinely slurred to "ampersand" and the term had entered common English usage by 1837.[4][6][7] However, in contrast to the 26 letters, the ampersand does not represent a speech sound—although other characters that were dropped from the English alphabet did, such as the Old English thorn, wynn, and eth. Through popular etymology, it has been falsely claimed that André-Marie Ampère used the symbol in his widely read publications and that people began calling the new shape "Ampère's and".[8] History[edit] Evolution of the ampersand The modern ampersand is virtually identical to that of the Carolingian minuscule. The italic ampersand, to the right, is originally a later et-ligature. Et ligature in Insular script Example of ampersand based on a crossed epsilon, as might be handwritten. Some modern fonts, like Trebuchet MS, employ ampersand characters that reveal its origin The ampersand can be traced back to the 1st century A.D. and the Old Roman cursive, in which the letters E and T occasionally were written together to form a ligature (figure 1). In the later and more flowing New Roman Cursive, ligatures of all kinds were extremely common; figures 2 and 3 from the middle of 4th century are both examples of how the et-ligature could look in this script. During the following development of the Latin script that led up to the Carolingian minuscule (9th century) the use of ligatures in general diminished. The et-ligature, however, continued to be used and gradually became more stylized and less revealing of its origin (figures 4–6).[9] The modern italic type ampersand is a kind of "et" ligature that goes back to the cursive scripts developed during the Renaissance. After the advent of printing in Europe in 1455, printers made extensive use of both the italic and Roman ampersands. Since the ampersand's roots go back to Roman times, many languages that use a variation of the Latin alphabet make use of it. The ampersand often appeared as a letter at the end of the Latin alphabet, as for example in Byrhtferð's list of letters from 1011.[10] Similarly, & was regarded as the 27th letter of the English alphabet, as used by children (in the US)[citation needed]. An example may be seen in M. B. Moore's 1863 book The Dixie Primer, for the Little Folks.[11] In her 1859 novel Adam Bede, George Eliot refers to this when she makes Jacob Storey say: "He thought it [Z] had only been put to finish off th' alphabet like; though ampusand would ha' done as well, for what he could see."[12] The popular Apple Pie ABC finishes with the lines "X, Y, Z, and ampersand, All wished for a piece in hand". The ampersand should not be confused with the Tironian "et" ("⁊ "), which is a symbol similar to the numeral 7. Both symbols have their roots in the classical antiquity, and both signs were used up through the Middle Ages as a representation for the Latin word "et" ("and"). However, while the ampersand was in origin a common ligature in the everyday script, the Tironian "et" was part of a highly specialised stenographic shorthand.[13] The Tironian "et" ("⁊ ") is found in old Irish language script, a Latin-based script generally only used for decorative purposes today, where it signifies agus ("and") in Irish. This symbol may have entered the script language by way of monastic influence in the time of the early Christian church in Ireland. Writing the ampersand[edit] In everyday handwriting, the ampersand is sometimes simplified in design as a large lowercase epsilon (Ɛ) or a backwards numeral 3 superimposed by a vertical line. The ampersand is also often shown as a backwards 3 with a vertical line above and below it or a dot above and below it. The + sign is often informally used in place of an ampersand, sometimes with an added loop and resembling ɬ. • Glyph No.1 of writing Ampersand[14] • Glyph No.2 of writing Ampersand[14] • Glyph No.3 of writing Ampersand[14] Usage[edit] Ampersands are commonly seen in business names formed from partnership of two or more people, such as Johnson & Johnson, Dolce & Gabbana, Marks & Spencer, A&P (supermarkets), and Tiffany & Co., as well as some abbreviations containing the word and, such as AT&T (American Telephone and Telegraph), R&D (research and development), R&B (rhythm and blues), B&B (bed and breakfast), and P&L (profit and loss).[15][16] In film credits for stories, screenplays, etc., & indicates a closer collaboration than and. The ampersand is used by the Writers Guild of America to denote two writers collaborating on a specific script, rather than one writer rewriting another's work. In screenplays, two authors joined with & collaborated on the script, while two authors joined with and worked on the script at different times and may not have consulted each other at all.[17][18] In the latter case, they both contributed enough significant material to the screenplay to receive credit but did not work together. In APA style, the ampersand is used when citing sources in text such as (Jones & Jones, 2005). In the list of references, an ampersand precedes the last author's name when there is more than one author.[19] (This does not apply to MLA style, which calls for the "and" to be spelled.[20]) The phrase et cetera ("and so forth"), usually written as etc. can be abbreviated &c. representing the combination et + c(etera). The ampersand can be used to indicate that the "and" in a listed item is a part of the item's name and not a separator (e.g. "Rock, pop, rhythm & blues, and hip hop"). The ampersand may still be used as an abbreviation for "and" in informal writing regardless of how "and" is used. Computing[edit] Encoding and display[edit] The character in Unicode is U+0026 & AMPERSAND (HTML & · & ); this is inherited from the same value in ASCII. Apart from this, Unicode also has the following variants: • U+FE60 ﹠ SMALL AMPERSAND (HTML ﹠ ) • U+FF06 ＆ FULLWIDTH AMPERSAND (HTML ＆ · in block Halfwidth and Fullwidth Forms) • U+214B ⅋ TURNED AMPERSAND (HTML ⅋ ) • U+1F670 � SCRIPT LIGATURE ET ORNAMENT (HTML 🙰 ) • U+1F671 � HEAVY SCRIPT LIGATURE ET ORNAMENT (HTML 🙱 ) • U+1F672 � LIGATURE OPEN ET ORNAMENT (HTML 🙲 ) • U+1F673 � HEAVY LIGATURE OPEN ET ORNAMENT (HTML 🙳 ) • U+1F674 � HEAVY AMPERSAND ORNAMENT (HTML 🙴 ) • U+1F675 � SWASH AMPERSAND ORNAMENT (HTML 🙵 ) The last six of these are carryovers from the Wingdings fonts, and are meant only for backward compatibility with those fonts. On the QWERTY keyboard layout, the ampersand is ⇧ Shift + 7 . It is almost always available on keyboard layouts, sometimes on ⇧ Shift + 6 or ⇧ Shift + 8 . On the AZERTY keyboard layout, & + is an unmodified keystroke, positioned above A . In URLs, the ampersand must be replaced by %26 when representing a string character to avoid interpretation as a URL syntax character. Programming languages[edit] In the 20th century, following the development of formal logic, the ampersand became a commonly used logical notation for the binary operator or sentential connective AND. This usage was adopted in computing.
