A mnemonic is a device, such as a formula or rhyme, used as an aid in remembering.
Mnemonic, or mnemonic device, stands for something that helps remembering. Mnemonics aim to translate an information into another form that the human brain can retain better than its original form.
Mnemonic widely uses visual and auditory associations.
For learning foreign languages, a common mnemonic tool is replacing or associating a difficult foreign word with a word in a language the learner is already aware about. It may require finding linkwords, words that are directly or indirectly linked with the new word and with the word being learned.
