What is an example of a memorable phrase used as a mnemonic?

The phrase "I before E, except after C" is a well-known mnemonic device used to help with the spelling of certain English words. It assists learners in remembering a common spelling rule regarding the sequence of the letters 'I' and 'E'. This rule is particularly useful in English because the positions of these letters can vary in different words, leading to confusion for many students. Mnemonic devices are most effective when they provide a catchy or memorable guideline that simplifies the learning process.

In contrast, while the other phrases have their own merits, they either do not correspond to widely recognized concepts or may not serve the same educational purpose effectively. For instance, although "Every good boy does fine" does serve as a mnemonic for music notes, it might not be as universally applicable across contexts as the spelling rule. Each catchy phrase supports learning by providing a simple way to recall more complex information.
