How to Sign "Probably"
To sign 'probably,' start with both hands in 'S' shapes (fists) in front of your chest, with your palms facing forward. Drop both hands downward a short distance while bending your wrists so your palms face downward. Because this sign is very similar to the signs for 'can' or 'possible,' it is essential to pair the movement with a slightly unsure facial expression. Pursing your lips or tilting your head slightly will perfectly convey the meaning of 'probably.'
