Word Origin and History for ampersand

1837, contraction of and per se and, meaning "(the character) '&' by itself is 'and' " (a hybrid phrase, partly in Latin, partly in English). The symbol is based on the Latin word et "and," and comes from an old Roman system of shorthand signs (ligatures), attested in Pompeiian graffiti, but not (as sometimes stated) from the Tironian Notes, which was a different form of shorthand, probably invented by Cicero's companion Marcus Tullius Tiro, which used a different symbol, something like a reversed capital gamma, to indicate et.

This Tironian symbol was maintained by some medieval scribes, including Anglo-Saxon chroniclers, who sprinkled their works with a symbol like a numeral 7 to indicate the word and. In old schoolbooks the ampersand was printed at the end of the alphabet and thus by 1880s had acquired a slang sense of "posterior, rear end, hindquarters."

ampersand in Technology
"&" ASCII character 38.
Common names: ITU-T, INTERCAL: ampersand; amper; and. Rare: address (from C); reference (from C++); bitand; background (from sh); pretzel; amp.
A common symbol for "and", used as the "address of" operator in C, the "reference" operator in C++ and a bitwise AND operator in several programming languages.
UNIX shells use the character to indicate that a task should be run in the background.
The ampersand is a ligature (combination) of the cursive letters "e" and "t", invented in 63 BC by Marcus Tirus [Tiro?] as shorthand for the Latin word for "and", "et".
The word ampersand is a conflation (combination) of "and, per se and". Per se means "by itself", and so the phrase translates to "&, standing by itself, means 'and'". This was at the end of the alphabet as it was recited by children in old English schools. The words ran together and were associated with "&". The "ampersand" spelling dates from 1837.
