American Sign Language is one of the fastest-growing languages in the United States today. American Sign Language, also known as "ASL", is a complex visual-spatial language used by the deaf community.
It is the mother tongue of many deaf men and women and some deaf children born into deaf families. ASL linguists earn various certificates through a special training and testing process to give best sign language assistance.

The certificate has 5 specific levels based on the test and desired level of proficiency. The levels are scaled from 1 to 5, with 5 being the most advanced level. ASL has no grammatical similarities to English and in no way should be viewed as a distorted, imitated, or gestural form of English.
Some people describe ASL and other sign languages as "sign languages". That's not entirely true, as hand gestures are just part of ASL.
Facial features such as eyebrow movements and mouth movements, as well as other factors such as body orientation, are also important in ASL because they are an important part of the grammatical system. In addition, ASL uses the space around the signer to describe places and people who are not present.
Sign language is developed specifically for their community and is not universal. At least 121 different types of sign language are spoken worldwide.
