What is a mnemonic device ?

A mnemonic device is a learning technique that helps people to remember information, usually by associating it with other, more easily remembered information. Mnemonic devices can take many forms, such as rhymes, acronyms, songs, or phrases that use the first letter of each word to create a memorable sequence. These devices are often used to help people learn new vocabulary words, facts, or other information that is difficult to remember through rote memorization alone. By using mnemonic devices, learners can make deeper, more lasting connections with information, which can help them to recall it more easily when they need it.
