The /m/ sound is a bilabial nasal – both lips press together while air flows through the nose. It pairs with other nasals and bilabials in ways that create a distinctive humming quality in M tongue twisters. Here are 8 of the best.
The Mad Cow (If You Must Cross)
If you must cross a coarse cross cow across a crowded cow crossing, cross the coarse cross cow across the uncrowded cow crossing.
The repeating “cross” in five grammatical roles – adjective, verb, noun, adjective again, verb again – is what defeats most speakers. A famous British tongue twister with a satisfying logic.
Many Mumbling Mice
Many mumbling mice are making midnight music in the moonlight.
A pure /m/ alliteration chain. Six of the eight content words begin with /m/. “Mumbling” and “midnight” and “moonlight” all have /m/ in their first syllable, creating a low humming rhythm that is deceptively hard to sustain at pace.
Moses Supposes
Moses supposes his toeses are roses,
But Moses supposes erroneously.
For nobody’s toeses are posies of roses
As Moses supposes his toeses to be.
Popularised by the 1952 film “Singin’ in the Rain,” this rhyme plays on “Moses,” “supposes,” “toeses,” “roses,” and “posies” – five near-rhymes that create a cascading /z/ chain. The nonsense word “toeses” (invented toes plural) is the main stumbling block.
Mix, Miss Mix
Mix, Miss Mix! Mix, Miss Mix! Mix, Miss Mix!
A minimal-pair challenge. “Mix” and “Miss” differ by only one sound – the final /ks/ versus /s/. At speed, “Miss Mix” becomes “Mix Mix” and “Miss Miss” interchangeably.
My Mother’s Monkey
My mother’s monkey met my mother’s moose.
Three /m/ words in a possessive chain – “mother’s monkey” and “mother’s moose” – with the repetition of “my mother’s” creating a loop. Say it five times without “monkey” and “moose” switching places.
Mummies Make Magic
Mummies make magic mischief in Memphis.
Five /m/ words in six. The /m/-/m/ doubling in “mummies make magic mischief” creates a near-continuous nasal hum that is easy to start but hard to maintain precisely.
Monday’s Max Made Mud
Monday’s Max made massive muddy mounds of messy moist mud.
A longer M-chain that ends with “moist mud” – the /st/ cluster in “moist” arriving after seven consecutive M words creates a jarring transition most speakers miss.
Moose Nibbling Mooselips
Moose nuzzling, murmuring, munching mellow mushrooms in misty marshes.
A tongue twister that sounds peaceful but is surprisingly hard to say at speed. Six of the seven content words begin with /m/, with “mellow” and “marshes” and “misty” all requiring distinct vowels after the /m/ onset.
Why Are M Tongue Twisters Hard?
The /m/ sound requires full lip closure, which interrupts the airflow completely for a brief moment. In rapid sequences, the lips do not always fully close before the next word begins, causing /m/ to sound like /b/ or /n/. “Many mumbling mice” becomes “bany bumbling bice” in the mouth of even a careful speaker at full speed.
Tips for M Tongue Twisters
- Exaggerate the lip closure for each /m/ – you should feel your lips pressing together firmly.
- For the Moses Supposes rhyme, fix the meaning of “toeses” as “toes” before you start – the nonsense word is harder to process than it looks.
- Hum the /m/ sound deliberately between words to keep the nasal quality distinct from /b/.
