How to sign "until" in American Sign Language (ASL)?
Meaning: Up to (the point in time or the event mentioned).
Pronunciation (sign description): Dominant upright forefinger held in space facing non-dominant upright index finger in a diagonal direction where both palms face each other; tip of dominant forefinger moves toward the tip of passive index finger in a slightly arc motion.
Learner tip: Don't confuse this with similar signword TO (a different movement parameter). Unlike TO, UNTIL has a longer and curved movement.
