A very basic definition is that chunking is a way of organizing information into familiar groupings. This is done with all sorts of information, including numbers, single words, and multiple-word phrases which are collapsed into a single word, to create acronyms. The main advantage of this type of mnemonic device is that it enhances retention and memory. For example, how do you remember the names of the 5 Great Lakes? If you just remember the acronym, HOMES, you may find it easier to remember that the names of the Great Lakes are Huron, Ontario, Michigan, Erie, and Superior.
