parts or major parts of a compound term; also: an abbreviation (as FBI). Chinese-based words ( Sino-Japanese vocabulary ) uses similar acronym formation to Chinese, like Tdai for Tky Daigaku Tokyo University ). Other conventions edit When a multiple-letter abbreviation is formed from a single word, periods are in general not used, although they may be common in informal usage. "Very deep multiply nested acronyms". 77 A classic real-world example of this is the name of the predecessor to the Apple Macintosh, The Apple Lisa, which was said to refer to "Local Integrated Software Architecture but was actually named after Steve Jobs's daughter, born in 1978. 35 In English, acronyms pronounced as words may be a 20th-century phenomenon. An example of creating a backronym for comedic effect would be in naming a group or organization, the name "A.C.R.O.N.Y.M" stands for (among other things) "a clever regiment of nerdy young men".
