Here's why it's difficult:
* Variable Number of Continents: There's debate about whether there are 7 or 6 continents (sometimes North and South America are combined).
* Letter Limitations: It's hard to find a memorable combination of letters that represents all continents, especially with varying starting letters.
If you're looking for a way to remember the continents, consider a mnemonic device like a phrase or rhyme:
Example:
* Never Ask Sally About Eating And Obviously Avoid Authentic And Awkward Antics. (North America, South America, Asia, Europe, Africa, Oceania, Antarctica)
