What term describes a word formed from the first initials of a title or phrase?

The term that describes a word formed from the first initials of a title or phrase is "acronym." Acronyms are typically created by taking the initial letters of a series of words to form a new, pronounceable term. For example, "NASA" is an acronym for the "National Aeronautics and Space Administration," where the first letters of each word are used to create a single word.

This process allows for easier communication and recall of longer phrases or titles, making it particularly valuable in contexts like professional education, where complex concepts often need to be referenced quickly and clearly. Acronyms can enhance understanding and retention of information by condensing lengthy terms into a simple and memorable format.

The other options do not fit this definition. For instance, abbreviation refers to any shortened form of a word or phrase but doesn't necessarily focus on using initial letters to form a new word. Phraseology pertains to the way in which words and phrases are used in a particular context, and symbolism involves using symbols to represent ideas or qualities. Thus, "acronym" is the most accurate term to describe a word formed from the first initials of a title or phrase.
