Acronyms vs. Abbreviations

[Margaret Lee]

Can anyone explain the _real_ difference (if there is one) between acronyms and abbreviations.  The _Introduction to Language_ text by Fromkin and Rodman defines acronyms as "words derived from the initials of several words," with examples such as NASA and UNICEF.

  However, they also say that "when the string of letters cannot be easily prononced as a word, the acronym is produced by sounding out each letter," with examples such as NFL and UCLA.  I always thought that if they could not be pronounced as words, they were just abbreviations, not acronyms. In other words, my thinking is, all acronyms are abbreviations, but not all abbreviations are acronyms.  In _The American Heritage Dictionary_, 'USMC' , for example, is listed as the *abbreviation* (not acronym) for United States Marine Corps. Should/can the two be used interchangeably?
  Any thoughts on this?
