Mnemonic

A mnemonic is like a trick to help you remember something. If a mnemonic is a sentence, each word in the sentence will start with a letter in the word you want to remember. For example, if you wanted to remember the colors of the rainbow (Red, Orange, Yellow, Green, Blue, Indigo, Violet), you could use the mnemonic "Roy G Biv," which stands for Red, Orange, Yellow, Green, Blue, Indigo, Violet.
