Welcome to ASL Unit 1 Parameters, where you’ll learn the five key features that make up every sign in American Sign Language. These parameters are like the building blocks of ASL—just as sounds form spoken words, parameters form signed words.
Understanding and recognizing these components will help you improve accuracy, avoid errors, and develop a stronger visual foundation for ASL fluency.
🎯 Learning Goals for Parameters
- Identify and define the five parameters of a sign
- Analyze signs by their components (handshape, location, etc.)
- Apply parameters when creating or comparing signs
- Recognize how small differences in parameters can change meaning
- Use parameter awareness to improve clarity and comprehension
🧱 The Five Parameters of a Sign
- Handshape – The shape your hand forms when making a sign
- Example: A, B, 5, G, C handshapes
- Palm Orientation – The direction your palm faces
- Example: Facing out vs. facing in can change meaning (e.g., MINE vs. YOURS)
- Location – Where the sign is made in relation to your body
- Example: SIGNS near the head, chest, or in front of the body
- Movement – The action or motion in the sign
- Example: Circular, up/down, side-to-side
- Non-Manual Signals (NMS) – Facial expressions, head movement, and body posture
- Example: Eyebrows raised for yes/no questions, chin raised for rhetorical questions
🧠 Applying Parameters in ASL
Compare:
- MOTHER vs. FATHER – same handshape and movement, but different location
- KNOW vs. THINK – similar location and movement, but different handshape
Create:
- Identify a new sign and break it down:
- Handshape?
- Palm orientation?
- Location?
- Movement?
- NMS?
✋ Cultural Notes
In Deaf culture:
- Precision matters—changing a parameter can change the word entirely
- ASL users often use classifiers and space, which rely on proper parameter use
- Facial expressions are just as important as hand movements when expressing emotion, grammar, or intensity
Awareness of parameters strengthens your connection to ASL as a full and expressive language.
🔁 Practice Activities
Parameter Breakdown Video
- Record yourself signing 3–5 familiar signs
- Watch and label the parameters for each one
Matching Game
- Show two similar signs (e.g., DEAF and THINK)
- Identify which parameter(s) are different
Peer Review
- Practice in pairs:
- Partner A signs a word
- Partner B identifies the 5 parameters
- Reverse roles and repeat
📖 Common Questions
Q: What happens if I get one parameter wrong?
A: The meaning can change completely—or be unclear. Always check palm orientation and location.
Q: Is NMS optional?
A: No. It’s a required part of ASL grammar and meaning, especially in questions or emotional expression.
Q: Do classifiers follow the same parameters?
A: Yes. Classifiers also rely on handshape, movement, and space—so parameters are essential there, too.
