It looks like you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer Acronyms
An acronym is a word made up from the first letters of a list of words. Here's how it works. You take the list of words or facts that you want to remember and put them in an order so that the first letters of each word, or the first syllables, spell a real word or a made-up word.
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
