Mnemonics anyone?

Some things are easier to forget than others. That’s why we have mnemonics. Derived from the Greek word mnemon (remembering), a mnemonic is a handy device that helps you to recall a difficult formula or sequence of words. Every English schoolchild’s favourite is probably ‘Richard Of York Gave Battle In Vain’, which I silently mouth in order to bring to mind the order of colours in a rainbow – Red, Orange, Yellow, Green, Blue, Indigo, Violet. There’s also the points of the compass – ‘Never Eat Soggy Waffles’. I’m keen to learn what memory aids are used by speakers of languages other than English.
