The sign for "many" also means "lots of."
MANY:
You can do the sign larger and with more facial expression to mean things
like, "very many!" "bunches!" "a ton of..." etc.
very-MANY:
Notes:
The sign for "MANY" doesn't
mean "how many" -- and you shouldn't just stick a "HOW" in front of
"MANY" and think that it means "how many" -- it doesn't (even though you
might see people doing it that way. It is a waste of effort.) The sign "how-MANY" is
similar to the sign "MANY" except that the sign "HOW-MANY" moves
upward and
uses a furrowed "wh-question" type of brow.
