I was informed this weekend about the differences between acronyms and initialism.

Acronyms are abbreviations such as:
MADD. (Mothers against drunk drivers) that can actually be pronounced as a word.

Initialisms are abbreviation s of words that do not make words that can be pronounced.
RBI: runs batted in

Sounded good to me. ..

and...?

i guess AA is a initialism since nobody would say they attend (AA) aahh meetings.
