Quick answer
To sign the letter M in ASL, fold your index, middle, and ring fingers down over your thumb so the thumb tip peeks out under the ring finger. Keep the palm facing outward. Three fingers draped over the thumb form the letter M.
How to Sign the Letter M in Sign Language
The letter M is part of the American Sign Language (ASL) manual alphabet used for fingerspelling. To make it, tuck your thumb in across your palm and fold your index, middle, and ring fingers down over it, so the thumb tip peeks out beneath the ring finger. Curl your pinky down too and keep your palm facing outward toward the viewer.
Think of M’s three humps in print mirroring the three fingers draped over the thumb. That mental link makes it easy to remember.
Step-by-Step: Forming the M Handshape
| Step | What to Do |
|---|---|
| 1. Hand position | Raise your dominant hand to about shoulder height. |
| 2. Tuck the thumb | Fold your thumb in across your palm. |
| 3. Drape three fingers | Fold the index, middle, and ring fingers down over the thumb. |
| 4. Pinky | Curl the pinky down as well. |
| 5. Orientation | Face your palm outward, thumb tip peeking out. |
Hold the shape so all three fingers clearly cover the thumb.
M vs. N: Telling Them Apart
M and N use nearly the same shape, so the number of draped fingers is the difference.
| Feature | Letter M | Letter N |
|---|---|---|
| Fingers over thumb | Three (index, middle, ring) | Two (index, middle) |
| Thumb tip shows | Under the ring finger | Under the middle finger |
| Memory cue | Three humps of “M” | Two humps of “N” |
Three fingers over the thumb make M; two fingers make N.
Common Mistakes to Avoid
- Covering only two fingers. That makes N — M needs three fingers over the thumb.
- Leaving the thumb out. The thumb must tuck under the folded fingers.
- Holding the fingers straight. The fingers should fold down, not point up.
- Turning the palm inward. M reads clearest with the palm facing the viewer.
Practice Tips for Fingerspelling M
Learn M inside short, common words rather than in isolation:
- MOM — M, O, M
- HAM — H, A, M
- ARM — A, R, M
- MAP — M, A, P
Spell slowly at first, keeping your hand in one steady spot near your shoulder and changing only your finger position between letters.
Where the Letter M Fits in the ASL Alphabet
M sits beside N in the group of letters formed by folding fingers over a tucked thumb. Learning the two together is efficient: master the drape-over-the-thumb shape once, then simply adjust how many fingers cover the thumb to switch between them. The “three humps” memory trick keeps M distinct, and a clean, compact handshape ensures it reads correctly inside spelled words as your fingerspelling speeds up.
Frequently Asked Questions
How do you sign the letter M in ASL?
Tuck your thumb across your palm and fold your index, middle, and ring fingers down over it. The thumb tip rests under the ring finger, so three fingers drape over the thumb. Curl the pinky down too and face your palm outward. Three fingers over the thumb make M.
What is the difference between M and N in sign language?
Both fold the fingers down over a tucked thumb, but the number of fingers differs. M drapes three fingers over the thumb (index, middle, ring), while N drapes only two (index and middle). Count the fingers covering the thumb to tell them apart.
How many fingers cover the thumb in the letter M?
Three fingers — the index, middle, and ring — fold down over the thumb. The thumb tip pokes out between the ring and pinky fingers. That three-finger drape is what distinguishes M from the two-finger N.
Why are M and N easy to confuse?
They use almost the same shape, with fingers folded over a tucked thumb and the palm facing out. The only difference is whether three fingers (M) or two fingers (N) cover the thumb, so signers must look closely at how many fingers are draped down.
How do I practice fingerspelling the letter M?
Drill M inside short words such as MOM, HAM, or ARM, holding the folded shape briefly each time. Keep your hand steady near your shoulder and change only your finger position between letters.
