How to sign "a" in ASL

How to Sign "A"

The letter “A” is fingerspelled with a closed fist and thumb beside the index finger:

• Make a fist with all fingers curled inward.
• Position the thumb alongside the side of the index finger—not inside.
• Hold orientation toward the viewer for clarity.

Tips

• Keep fist compact—don’t tuck thumb inside fist.
• Maintain clear viewing orientation for the viewer.

Common Mistakes

• Thumb tucked under fingers—that’s incorrect.
• Using open hand instead of closed fist.

Think: “Fist closed, thumb beside index—A.”
