Silly sentences that lock
lists in your brain
Quick question. What are the colours of the rainbow, in order? If you said "Red, Orange, Yellow, Green, Blue, Indigo, Violet" — congratulations, you just used a memory trick. You probably learned it using "Richard Of York Gave Battle In Vain."
What it is
A mnemonic (pronounced "ne-MON-ick" — the M at the start is silent) is a memory trick that helps you remember lists, sequences, or anything boring that your brain doesn't naturally want to keep.
Your brain remembers weird, funny, or vivid things way better than it remembers boring things.
A flying purple elephant wearing sunglasses? Easy to remember. A list of seven cranial nerves? Almost impossible.
But what if you turned the list into a funny sentence? Suddenly the impossible becomes easy. That's the whole trick. You take boring information and attach it to something your brain naturally wants to remember.
The main types
1. Acronyms
Take the first letter of each item and turn it into a word.
- CIA — Confidentiality, Integrity, Availability
- SMART goals — Specific, Measurable, Achievable, Relevant, Time-bound
2. Acrostics (silly sentences)
If the first letters don't make a word, you make a sentence instead.
- "Richard Of York Gave Battle In Vain" — Red, Orange, Yellow, Green, Blue, Indigo, Violet
- "My Very Educated Mother Just Served Us Noodles" — Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
3. Rhymes
Catchy rhymes lock dates and rules into your brain.
- "Thirty days hath September, April, June, and November..."
- "In 1492, Columbus sailed the ocean blue."
4. Memory palaces
You imagine a familiar place — your bedroom, your route to school — and you "place" each thing you need to remember in different spots.
Need to remember 10 things? Walk through your house in your head. The kitchen has a giant talking banana. The hallway has a robot doing the cha-cha. The bathroom has a tiny dragon brushing its teeth. Each weird image is one fact.
Memory champions use this trick to memorise entire decks of cards.
A kid using it
Meet Theo. He's in Year 6. He has to learn the order of the eight planets for a science test.
He could try to memorise the list — Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. But it's just eight random words. His brain doesn't want to keep them.
So Theo uses the acrostic: "My Very Easy Method Just Speeds Up Naming."
- My → Mercury
- Very → Venus
- Easy → Earth
- Method → Mars
- Just → Jupiter
- Speeds → Saturn
- Up → Uranus
- Naming → Neptune
He says it three times. Easy. He can now name all eight planets in order, six months later, without thinking.
Build your own memory trick for something you're studying.
- Pick a list, sequence, or set of facts you need to memorise
- Look at the first letter of each item
- Can you make a real word from them (acronym)? If yes, great.
- If not, can you make a sentence where each word starts with the right letter (acrostic)?
- Run your sentence past a grown-up. Does it sound silly enough to remember?
- Test yourself the next day. Can you say the list using only your sentence?
The sillier the sentence, the better. Funny things stick.
The reason memory palaces work so well is that your brain has a special memory system just for places. It's the same system humans used for thousands of years to remember which forests had food and which had bears.
When you attach information to a location — even an imaginary walk through your house — you're tapping into that ancient memory system. It's much stronger than the system you use for facts.
Mistake 1 — Building a mnemonic that's harder than the list. If your sentence is harder to remember than the actual list, you've failed. Keep it short. Keep it weird. Keep it simple.
Mistake 2 — Using mnemonics for stuff you should actually understand. Memory tricks help you recall specific items. They don't help you understand how things work.
If you need to understand HOW photosynthesis works, use Teach a Teddy. If you need to remember the ORDER of the planets, use a mnemonic. Different jobs, different tools.
Quick check
1. What's the difference between an acronym and an acrostic?
An acronym is when the first letters spell a real word (CIA). An acrostic is when they spell a sentence (Richard Of York Gave Battle In Vain).
2. Why do silly or weird mnemonics work better than serious ones?
Because your brain remembers weird and funny things better than boring ones.
3. When should you NOT use a memory trick?
When you need to understand a concept, not just memorise a list. For understanding, use the Feynman Technique instead.
Take a boring list. Turn it into something weird, funny, or vivid. The weird thing sticks — and the list sticks because of the weird thing. Make your own. Test it. Use it. Just remember: memory tricks are for memorising, not for understanding.
