: TLA = Three Letter Acronym (like "IBM" ;^)
: ETLA = Extended TLA, where three aren't enough.
: In my years at IBM, I actually ran into nested TLAs where one or more : of the letters stood for another TLA and sometimes the nesting went : three levels. I can't think of any examples; this whole topic is : making my brain hurt.
I'd be interested in seeing some of those.
There's also recursive acronyms, where one of the letters stands for the overall acronym, e.g., SAAB (Saab Automobile Aktiebolaget), and VISA (VISA International Service Association).
And there's a type I don't know the name of, but where one of the words represented in the acronym appears elsewhere in the overall term. ADAP (a chain of East Coast auto parts dealers) was originally American Discount Auto Parts, but was later renamed ADAp Discount Auto Parts.
