Definition of ACRONYM is defined incorrectly as an "abbreviation made from the initial letters", but it should be "abbreviation made from non-contiguous letters of a name or phrase". These are usually the initial letters, but not always; the name being abbreviated is usually made up of more than one word, but not always; and the acronym sometimes contains extra letters that don't occur in the original phrase, but are added in to aid in pronunciation.
Proposed Change:
Change to "abbreviation made from non-contiguous letters of a name or phrase".
We have revised the definition to read, "abbreviated form made from the initial letters or parts of other words (in a name or phrase) which may be pronounced as a word."
