How do I show that 'fell' happened in the past?
In ASL, verbs don't change form for past tense. You use the same sign for 'fall' and 'fell.' To show it happened in the past, you establish the time frame (like 'yesterday' or 'past') at the beginning of your sentence.
Can I use this sign for a tree falling?
No, this specific sign uses the 'V' handshape, which represents a person with legs. For a tree falling, you would use a different classifier, typically an upright forearm that tips over to represent a tall, cylindrical object falling.
Does the speed of the sign matter?
Yes! ASL is very expressive. If you sign the falling motion quickly and forcefully, it shows a hard, sudden fall. If you sign it slowly, it might imply a slow, dramatic tumble or slipping.
