from Indiana asks:
Is the sign "FULL" interchangeable with the sign for full that is dominant
hand palm down and moved from mid-abdomen to chin? Or are they different
kinds of full? Or, is it an "Indiana" thing?
Response:
No. These are two different concepts: FULL-(general) and "full"-(of
food, "had it up to here) are not interchangeable.
"Full"-(of food, "had it up to here") is only used for concepts like "I can't
eat any more" or "I've had it up to here with you!"-(requires proper facial
expression "angry")
PLENTY:

writes:
When signing "good-enough" do u sign good and then enough?
Response: Sort of. What you do is you combine the two signs into one smooth
movement.
It actually looks as if you were signing "BAD-ENOUGH" because the dominant
hand twists palm downward as it changes into the sign for ENOUGH. Note: In
this "compound version" of "GOOD-ENOUGH" the sign for "ENOUGH" only uses a
single movement. You use the first part of the sign GOOD and the last
part of the sign ENOUGH.
