Re: More like an acrostic
Duncan wrote:No, it's not an acronym (e.g. NASA or SCUBA), but more like an acrostic. Still, there is a word for this type of thing - people often do it at weddings or funerals where they take each letter of a person's name and use it as the first letter of an adjective to tell you something about the person.
Duncan,
Acronym is an inclusive word that includes these various subsets. An acrostic
is an acronym for example.
What you described
is a backronym. It might have another even more specific term for your specific description but that does in no way mean that it's not also a backronym, initialism and an acronym.
The examples you cited are all three, even if you might be looking for another word.
The logic is similar to:
"All men are humans but not all humans are men". Acronym is the inclusive term with subsets getting into specific types of acronyms.
