Always Writing b and d Backwards? Memorize Mirror Letters Once and for All with 'Fists' and 'a Bed'

Always Mix Up b and d? Remember Mirror Letters Once and for All with "Fists" and "A Bed"

You want to write bed, but it turns into deb; you want to write big, but it ends up as dig. Even though you recognize every letter, they get flipped left and right as soon as you start writing. This is completely normal—the four letters b, d, p, q are born looking like mirror images of each other, and even many children have to practice for a long time to tell them apart.

The good news is: there are a few body-memory tricks to distinguish them without rote memorization. Today, we'll explain the fist gesture, shape association, and an incredibly useful spelling rule all at once. After reading this, you'll walk away with three handy ways to tell them apart—just do a quick mental check before writing the letters next time.

First, Understand: Why These Four Letters in Particular?

Actually, b, d, p, and q are the exact same circle and stick, just with the circle swapped left-to-right and the stick swapped up-and-down:

• b: The stick is on the left, the circle is on the right, and the stick points up.
• d: The stick is on the right, the circle is on the left, and the stick points up.
• p: The stick is on the left, the circle is on the right, and the stick points down.
• q: The stick is on the right, the circle is on the left, and the stick points down.

See it? b and d are left-right opposites (mirror images), while b and p are up-down opposites (whether the stick goes up or down). Our brains are naturally not very good at distinguishing "horizontally flipped" shapes, so writing them backward is very common. The following tricks will give each letter a fixed sense of direction so you don't have to guess anymore.

Trick 1: Make Two Fists, and b and d Instantly Separate

This is the fastest, most useful trick, and you can do it anytime, anywhere:

Make a fist with both hands, give a thumbs-up with both thumbs pointing up, and then bring both fists together, facing you.

• Your left hand looks just like a b (the thumb is the stick on the left, and the fist is the circle on the right).
• Your right hand looks just like a d (the thumb is the stick on the right, and the fist is the circle on the left).

Left hand is b, right hand is d, and they perfectly match the order of the alphabet: b comes before d, just like your left hand comes before your right hand (when reading from left to right). If you get stuck in the middle of writing, just make a secret fist under the table to check, and you'll have your answer instantly.

• I read a big book. (I read a thick book.)
• Let's dig a hole in the sand. (Let's dig a hole in the sand.)

Trick 2: bed Is "A Bed"

The second trick is specifically for direction when spelling words. In your mind, imagine the English word bed as a side view of a bed:

• The starting b: The stick is on the left and the circle is on the right, like the headboard of a bed standing on the left.
• The ending d: The stick is on the right and the circle is on the left, like the footboard of a bed standing on the right.
• The middle e: This is the mattress you lie on.

So from left to right, a bed is "headboard (b) — mattress (e) — footboard (d)", which spells out b-e-d. As long as you remember "b is at the headboard, d is at the footboard", whenever you encounter these two letters in any word in the future, you can recall this picture of a bed to determine which side the stick should be on.

• I am so tired. I want to go to bed. (I'm so tired. I want to go to sleep.)
• Time for bed! (Time for bed!)

Commit this picture of a bed to memory; it's your portable compass for direction.

Trick 3: For p and q, Look at "Whether the Stick Goes Up or Down"

Once b and d are sorted out, you're left with p and q. Their sticks both hang down (like a tail hanging down), so the biggest difference from the upward-reaching b and d is:

Stick goes up, staying in the middle → b or d; Stick goes down, with a tail hanging below → p or q.

So how do you tell p and q apart? Use the same sense of direction from the first trick:

• p: The stick is on the left, on the same side as b (both on the left).
• q: The stick is on the right, on the same side as d (both on the right).

A handy rule of thumb: in the alphabet, p comes before q, just like b comes before d—the one on the left comes first.

• Please write your name here. (Please write your name here.)
• I have a question. (I have a question.)

Trick 4: When You See q, It's Almost Always Followed by u

This trick is a safety net for spelling that will help you avoid more than half of your mistakes. In English, q is almost always followed by u: queen, quick, quiet, question, quiz... there are almost no exceptions (except for a few loanwords, which you don't need to worry about).

So think of it the other way around:

• If you are about to write a word and the next letter is u, that letter is very likely q (quick, quiet).
• If the next letter is not u, then it is probably p, b, or d, and usually not q.

Remember this rule in one sentence: "q is never lonely; it always holds hands with u." If you're halfway through writing and unsure if it's a q, just check if there is a u following it.

• The queen lives in a big castle. (The queen lives in a big castle.)
• Please be quiet in the library. (Please be quiet in the library.)

Practice with Minimal Pairs: Just One Letter of Difference

To turn these tricks into reflexes, the most effective way is to practice with words that differ by only one letter. Write and read them slowly, group by group, to feel the difference in direction:

• big (large) / dig (to dig) — Does it start with b or d? Think of the fists.
• bad (bad) / dad (dad) — Is the stick of the first letter on the left (b) or the right (d)?
• pin (pin) / bin (bin) — The stick going down with a tail is p, and the stick going up is b.
• pig (pig) / big (large) — The stick hanging down is p, and the stick reaching up is b.

Remind yourself when writing: think of the direction first (the fists or the bed), then put pen to paper. You can start slowly and write larger at first, then speed up once you get the hang of it.

True/False Quick Practice: See If You've Got the Trick

Below are common cases of writing them backward; take a look and compare:

• Bed: bed ✓, deb ✗ (Remember: headboard b, footboard d)
• Large: big ✓, dig ✗ (dig means "to dig," which changes the meaning completely)
• Queen: queen ✓, pueen ✗ (q is followed by u, and the stick is on the right)
• Quiet: quiet ✓, qiet ✗ (Don't forget the u after q)

Don't be discouraged if you write them backward; beginners all over the world get stuck on these four letters. Being able to write bed and big correctly today is already solid progress—give yourself a round of applause.

How to Practice on Loopy

Loopy puts these letters into real-life contexts that you can see, hear, and write, turning recognition into a natural reaction:

• Dictionary Pronunciation: Look up words like bed, big, queen, and quiet one by one, and listen to the pronunciation models while looking at the letter shapes. Connect "what the word looks like" with "what it sounds like."
• Graded Courses: Choose courses according to your A1–B1 level, and naturally encounter words containing b, d, p, and q in real sentences over and over again. The more you see them, the more your hand will remember the direction.
• Listen and Repeat: Read aloud along with the sentences to consolidate the word's "form, sound, and meaning" together, instead of just memorizing isolated letters.
• Memory Curve Review: Learned words will reappear just when you are about to forget them, making the correct letter shapes a part of your muscle memory.

Take a placement test first to find your ideal starting point, then start with just a few words a day, and practice b, d, p, and q until you can tell them apart at a single glance.
