How to Sign "Last Name"

The sign for 'last name' is a combination of two signs: 'last' and 'name'. First, make 'I' handshapes with both hands by extending only your pinky fingers. Hold your non-dominant hand out, and strike its pinky with the pinky of your dominant hand as it moves downward. Then, immediately change both hands to 'H' handshapes (index and middle fingers extended together). Tap the fingers of your dominant hand crosswise over the fingers of your non-dominant hand twice.

Examples Using "Last Name" in a Sentence

1

What is your last name?

To sign this, point to the person for 'YOUR', sign 'LAST NAME', and finish with the sign for 'WHAT'. Remember to furrow your eyebrows at the end, as this is a wh-question.

2

My last name is Smith.

Point to yourself for 'MY', sign 'LAST NAME', and then clearly fingerspell S-M-I-T-H. You do not need a separate sign for the word 'is'.

3

We have the same last name.

Sign 'WE', then 'SAME', and finally 'LAST NAME'. When signing 'SAME', you can move the 'Y' handshape back and forth between you and the other person to show the shared connection.

How to Sign "Last Name"
The sign for 'last name' is a combination of two signs: 'last' and 'name'. First, make 'I' handshapes with both hands by extending only your pinky fingers. Hold your non-dominant hand out, and strike its pinky with the pinky of your dominant hand as it moves downward. Then, immediately change both hands to 'H' handshapes (index and middle fingers extended together). Tap the fingers of your dominant hand crosswise over the fingers of your non-dominant hand twice.
Visual Logic(Etymology)
This is a compound sign made of 'last' and 'name'. The sign for 'last' uses the pinky fingers, which are the final fingers on the hand, visually symbolizing the end or the last item in a sequence. The sign for 'name' is thought to originate from the historical tradition of signing an 'X' on a legal document, with the crossed fingers representing a signature.
Signing Tips
When signing 'last name', focus on a smooth transition between the two parts. You do not need to pause between 'last' and 'name'; let the downward motion of 'last' flow naturally right into the 'H' handshapes for 'name'. Keep your non-dominant hand relatively still in front of you to act as a base for both parts of the sign.
Common Mistakes
A common mistake is using the wrong fingers for either half of the sign. Remember that 'last' uses the pinky fingers, while 'name' uses the index and middle fingers. Additionally, beginners sometimes forget to tap the fingers twice for 'name'. Tapping only once changes the meaning from the noun 'name' to the verb 'to name' or 'called'.
Regional Variations
This sign is widely used and understood across the ASL community with minimal regional variation.

Frequently Asked Questions
Do I have to sign 'last name' or can I just fingerspell it?

While you will always fingerspell your actual surname, you should use this compound sign when asking for someone else's or referring to the concept of a surname. It is much faster and more natural in ASL than fingerspelling the English words 'L-A-S-T N-A-M-E'.

Why do we tap 'name' twice?

In ASL, nouns typically have a repeated, smaller movement, while verbs have a single, larger movement. Tapping the fingers twice indicates the noun 'name', whereas a single tap means the verb 'to name' or 'to be called'.

Can I use the 'last' part of this sign for 'last week'?

No, the sign for 'last' used here specifically means 'final' in a sequence. For time-related concepts like 'last week' or 'last year', ASL uses entirely different signs that involve moving backward over the shoulder to indicate the past.

ASL is a beautiful, expressive language. Practice regularly and have fun!
