Keyword method is a memory technique or mnemonic which generally uses visualization.
For instance, a student has to memorize the vocabulary “jaundice” which is mainly characterized by “yellowish skin”. He realizes that "Jaundice" sounds like “juice” which he closely associated with “orange or mango juice”. Another student associates the first syllable “jaun” with sound of a popular name, “John”. Hence, every time he sees the word jaundice, he imagines someone named John drinking mango juice which eventually makes his skin turn yellow. The more bizarre the image, the better. This technique is backed up by the research finding that a big part of memory work is influenced by visual input.
