An acronym is a word formed from the initials of words in a phrase to create a shortened word. Acronyms can be useful when remembering words in a specified order; however, it must be noted that they do not aid in understanding. Some examples of common acronyms include SCUBA (Self Contained Underwater Breathing Apparatus) and NATO (North Atlantic Treaty Organization). FBI (Federal Bureau of Investigation) and NRL (National Rugby League) are, technically, examples of initialism.

Below is an example of how acronyms can be used effectively to memorise the body parts of an insect.

The body parts of an insect include head, antennae, mouthparts, thorax, wings, legs, and abdomen. If you take the first letter from each of the words, you have the acronym HAMTWLA. By arranging the letters so that the acronym resembles a word/s you are familiar with, for example MATH WAL, it will be easier for you to remember.
