American Sign Language vs British Sign Language: What Makes Them Different?
American Sign Language (ASL) and British Sign Language (BSL) are distinct languages with different origins, grammar, vocabulary, and cultural contexts despite both countries speaking English. ASL was influenced by French Sign Language, while BSL developed independently in the UK. They use different signs for many words, and their fingerspelling systems differ—ASL uses one hand, BSL uses two. Their sentence structures and non-manual signals like facial expressions also vary. These differences mean ASL and BSL users typically cannot understand each other without learning the other language or using an interpreter. Learning the right sign language depends on your region and goals, with ASL being the best choice for North America. Both languages represent rich Deaf cultures and communication beyond spoken words.

Many people think sign language is the global language of Deaf people. Over 300 sign languages exist worldwide, each with its unique syntax. American and British sign languages are often compared. Despite both nations speaking English, ASL and BSL are quite different. Let's examine their differences.
Origins and History
ASL and BSL differ greatly in origins. In 1817, French educator Laurent Clerc co-founded the first U.S. deaf school. His influence changed ASL vocabulary and structure.
British Sign Language developed independently in the UK. French Sign Language didn't impact it, and British Deaf people have used it for generations. ASL and BSL evolved distinct signals, syntax, and cultural backgrounds.
Same word, different signs
Many learners are surprised to realise that ASL and BSL have little terminology in common. Linguists think that only 30% of signals are very similar. The ASL “hello” sign is different from the BSL one. Fluent ASL users cannot immediately comprehend BSL, and vice versa.
The distinction makes learning one over the other unique. Make sure your online ASL program focusses on ASL, not BSL or another version.
Alphabet, Fingerspelling
Fingerspelling also differs greatly. ASL users can spell words with one hand using a one-handed alphabet. This efficient method is popular throughout North America.
BSL's two-handed fingerspelling method is more difficult for single-handed communicators. This alone may hinder communication between signers from the two nations.
Grammar, Sentence Structure
Not only visual representations of spoken language, sign languages are whole languages. They have different grammar, sentence patterns, and syntax. ASL has a topic-comment format that starts sentences with the primary concept.
BSL organises phrases by time, subject, object, and verb, according on context. Switching languages requires rethinking how ideas are formed and communicated, not merely memorising new signals.
Non-Manual Signals and Expressions
ASL and BSL use facial expressions and body language to transmit tone, emotion, and grammar. The usage of non-manual signalling varies greatly. Raised eyebrows signify yes/no in ASL, however BSL may utilise various signals.
These slight distinctions show that sign languages are as complex as spoken languages and have regional and cultural peculiarities.
Learning Options: Choosing the Right Path
Start with the correct dialect if you want to learn sign language. North Americans and anyone seeking to communicate with Deaf people in the U.S. or Canada should take an American Sign Language online course.
Several reliable sites provide interactive ASL programs that lead to online certificates. These programs provide a complete linguistic foundation including fingerspelling, vocabulary, grammar, and culture. Make sure the program teaches ASL, not BSL, before joining.
Cultural Identity and Context
Deaf groups who utilise ASL and BSL have a strong cultural connection to language. British and American deaf cultures have different norms, values, and social structures. Learning any sign language entails entering that culture and knowing its history, difficulties, and community dynamics.
In ASL, narrative and visuals are important cultural expressions. Understanding the diverse characteristics of British Deaf culture will help learners communicate more effectively and respectfully.
Is Mutual Intelligibility Possible?
Can ASLers comprehend BSL? Usually not. The two languages are as distinct as spoken English and Japanese due to syntax, vocabulary, and signing methods. Gestures and body language may aid in certain contexts, but comprehensive talks normally need an interpreter or extensive cross-training.
International Sign (IS), a simplified, informal sign language used internationally, may facilitate international meetings and cooperation but is not a language.
Conclusion
Deaf people can communicate in ASL and BSL, although they have different norms, terminology, and cultural connotations. Understanding these differences is crucial whether you seek an online ASL certificate or are simply interested in sign languages.
By taking a respected American Sign Language online course, you may master the language and learn about a lively and varied culture that communicates without words yet says volumes.
