Here are some common ways to sign "more" in ASL:
* "More" as a general concept: The sign for "more" is similar to the sign for "again," but you make a small circular motion with your dominant hand, moving it slightly upwards.
* "More" referring to a specific item: You would use the sign for the item and then use the "more" sign described above. For example, if you want more "water," you would sign "water" and then the "more" sign.
* "More" asking for a specific quantity: You can use the sign for a number, followed by the sign for "more." For example, if you want "three more," you would sign "three" and then the "more" sign.
It's important to note that sign language is very visual and contextual, so observing how native signers use the signs for "more" is the best way to learn how to use them correctly.
