Why the 'sign language follows spoken language' myth persists
It's an intuitive but incorrect assumption that a country's sign language should mirror its dominant spoken language, since both English-speaking countries use English in writing. In reality, sign languages evolve within Deaf communities somewhat independently of the surrounding spoken language, which is exactly why ASL and BSL differ so much despite both existing alongside English.
Interpreting is its own skilled profession
Being conversationally fluent in ASL is different from being qualified to interpret in medical, legal, or educational settings, which generally requires additional specialized training and, in the US, certification such as through the Registry of Interpreters for the Deaf (RID).
Frequently Asked Questions
Is ASL just English spelled out with hand signs?
No β that description more closely matches fingerspelling or Signed Exact English, not ASL itself. ASL has its own independent grammar and sentence structure distinct from English.
Can someone who knows ASL understand British Sign Language?
Not automatically β ASL and BSL are distinct languages with different vocabularies and, notably, different manual alphabets (ASL uses one hand for fingerspelling, BSL uses two), so fluency in one doesn't transfer directly to the other.
How long does it take to become fluent in ASL?
It varies widely by person and study intensity, similar to learning any other language, and true fluency is generally measured in years of consistent practice rather than weeks or months, though basic conversational signs can be picked up much faster.
Do all Deaf people in the US use ASL?
Most Deaf Americans who sign use ASL, but not universally β some rely on other communication methods, such as lip-reading and spoken English, cued speech, or other sign systems, and preferences vary based on individual background, upbringing, and education.
