Frequently Asked Questions
Is ASL the same as English Sign Language?
No. American Sign Language (ASL) is a complete, independent language with its own grammar and syntax. British Sign Language (BSL) and other national sign languages are all distinct from ASL.
How many signs does ASL have?
ASL has tens of thousands of signs. This dictionary covers over 5,000 of the most commonly used signs in everyday, academic, professional, and medical settings.
Can I learn ASL from a dictionary alone?
A dictionary is a great reference, but for fluency you’ll also want to practice with other signers and take structured courses. Use this dictionary alongside our free ASL learning resources.
Are the signs standard across the US?
Most signs are widely understood across the US, but like spoken English, ASL has regional variations. The signs taught here reflect common mainstream American usage.
