ASL sign variation?

Question

I noticed that there are multiple signs for one word. How do i know which one to use?

Answer 1

Yes, variation exists in ASL just like spoken languages. There are several factors that cause sign variations. They are: 

1. Regional - for example the sign for HOSPITAL is different in New York than the rest of the U. S.
2. Age 
3. Gender - males tend to sign at lower locations (or non-citation form) while females tend to sign at higher locations (citation forms). Females also tend to use more pronouns. 
4. Ethnicity 

Obviously, if a sign has variation, there is no right or wrong one to use. However, consider these two things when deciding which variation of a sign to use: 

1. Your region 

2. Your teacher.  

What variation is used most often there? What variation does your teacher use?

Answer 2

what word?
