Sign language is not universal.

There are over 300 different variations of sign language across the globe that correspond to various spoken languages. Sign language is a remarkable and vibrant way to communicate, transcending spoken language's limitations. Used by millions, particularly within the deaf and hard-of-hearing communities, sign language is often thought to be universal. However, this notion is misleading. Just as each region has its native language, sign languages vary widely, each shaped by its own culture and history.

In this article, we’ll explore whether sign language is universal. We'll also list five compelling benefits of learning it, and a handful of books to help you get started.

What is Sign Language?

Sign language is a visual-gestural language that uses hand shapes, facial expressions, and body language to convey meaning. Unlike spoken languages, which rely on vocal sounds, sign languages are entirely visual and follow their unique paths of development. Each country or region has its sign language, such as American Sign Language (ASL), British Sign Language (BSL), and French Sign Language (LSF). These languages are not merely visual representations of spoken languages but have their own grammar, vocabulary, and syntax. For instance, ASL has roots in French Sign Language and has evolved independently, while BSL has developed within British culture. This diversity highlights the richness and complexity of sign languages around the world.

Sign languages are independent of spoken languages and follow their paths of development

Sign languages aren’t just versions of spoken languages—they have their history and evolved in their own way. Take American Sign Language (ASL), for example. It started in the U.S. in the early 1800s, influenced by French Sign Language and local signs people were already using. On the flip side, British Sign Language (BSL) has its roots in the UK’s culture and history. What’s cool is that sign languages develop based on the unique experiences of the deaf communities using them. They aren’t tied to the spoken languages around them, and that’s why they deserve to be seen as languages in their own right.

Each country or region has its own sign language, such as American Sign Language (ASL), British Sign Language (BSL), and French Sign Language

Every region or country has its sign language. ASL is mainly used in the U.S. and parts of Canada, BSL in the UK, French Sign Language (LSF) in France and Belgium, and German Sign Language (DGS) in Germany and Austria. And that’s just a few examples—there are over 300 different sign languages around the world! Each one has its grammar, vocabulary, and structure, and they’re not just mimicking spoken languages. They reflect the history and culture of the people who use them, which is why the variety of sign languages is so important.

Examples of sign languages demonstrate their unique characteristics and complexities

What’s interesting is how different sign languages can be from one another. For example, ASL usually follows a subject-verb-object order, like “I eat pizza,” while BSL might say the same thing in a subject-object-verb order, like “I pizza eat.” LSF uses a lot of facial expressions and handshapes, while DGS has a unique finger spelling system. These differences show just how diverse and complex sign languages are. They’ve all got their own personalities, and that’s what makes them so fascinating—and why they should be respected as individual languages.

The Diversity of Sign Languages

The idea of a “universal sign language” might sound appealing, but it doesn’t hold up against reality. Just as you wouldn’t expect a French speaker to understand Mandarin, the same goes for sign languages. For instance, American Sign Language (ASL) is entirely different from British Sign Language (BSL) and Australian Sign Language (Auslan). Each of these languages has its grammar, vocabulary, and unique characteristics. Chinese Sign Language (CSL) has a rich history, tracing its origins back to the first school for the deaf in 1887, and its signs often resemble written Chinese characters.

These differences arise from the cultural contexts in which these languages developed. ASL has roots in French Sign Language and incorporates elements from various regional dialects, while BSL has its distinct evolution. Recognizing these variations is crucial to appreciating the richness of sign languages. Irish Sign Language (ISL), for example, shares similarities with American Sign Language and includes unique gender-specific signs.

However, despite these differences, sign languages share common features. Most rely on visual and manual modalities, emphasizing gestures, facial expressions, and body language to convey meaning. This shared characteristic underscores a universal human need for connection and communication, demonstrating our adaptability in finding ways to express ourselves. Russian Sign Language (RSL) has historical connections to both American Sign Language and French Sign Language, illustrating the complex relationships among sign languages.

Spanish Sign Language (LSE) is another example, used by nearly 100,000 people in Spain, and it features regional variations similar to spoken languages. This highlights the uniqueness of each sign language and the influence of regional dialects.

No, sign language is not universal, and there is no single international sign language

It might sound appealing to think there's one universal sign language that everyone could understand, but that's not the case. There is no single sign language that is understood and used by all sign language users worldwide. While International Sign (IS) exists and is used at international deaf conferences and events, it is not a language in its own right. Instead, IS is more of a simplified system that helps people from different countries communicate, using signs that are common across different sign languages. But it doesn’t replace the unique sign languages that exist in different regions and countries. This just goes to show how diverse and individual sign languages are worldwide.

And Here’s Why

The reason there’s no universal sign language is similar to why there’s no universal spoken language. Just like spoken languages are shaped by the culture, history, and social norms of the communities that use them, sign languages are influenced by the unique experiences of the deaf communities they come from. This variety isn’t a limitation—it’s a reflection of the richness of human culture and experience. Each sign language has its own unique charm and characteristics, and this diversity shows us just how creative human communication can be. The variety of sign languages around the world enriches our understanding of communication and highlights human adaptability.

Benefits of Learning Sign Language

1. Enhancing Communication Skills

One of the most immediate advantages of learning sign language is how it can enhance your overall communication skills. When you start learning to sign, you become more attuned to non-verbal cues—something that’s crucial in all forms of communication. In sign language, things like facial expressions and body movements add layers of meaning, and being able to recognize these nuances can transform how you interact with others.

For example, a single sign can convey different emotions depending on how it’s expressed. This focus on non-verbal communication can lead to a greater appreciation of body language and tone in spoken conversations. As you learn to interpret these cues in sign language, you may find yourself becoming more aware of what others are truly trying to say, which helps reduce misunderstandings and fosters clearer, more meaningful conversations.

Additionally, learning sign language often improves your listening skills. In a world where distractions abound, focusing on visual language encourages you to engage fully with the speaker, sharpening your ability to understand and participate in conversations.

2. Fostering Inclusivity and Accessibility

Learning sign language can make a real difference, a powerful step toward fostering inclusivity and accessibility, particularly for deaf and hard-of-hearing individuals. Communication barriers can lead to feelings of isolation, and when more people know sign language, it creates opportunities for genuine engagement. Suddenly, deaf individuals can participate in conversations, social events, and community activities more freely. Even in regions with the same spoken language, sign languages can differ significantly, developing unique characteristics that highlight the importance of learning and understanding these diverse forms of communication.

Imagine going to a restaurant or a movie and not being able to understand what's going on. It's frustrating, right? Learning sign language can help fix that.

Think about it: when public spaces lack accommodations for the deaf community, it can be isolating for those who are deaf or hard of hearing. By learning sign language, you actively contribute to building environments where everyone feels welcome and included. This not only enhances social interaction but also promotes a culture of understanding and respect.

It's not just about being nice; it's about showing that everyone matters. When we create places where everyone feels welcome, we're saying, 'You belong here.' And that's important.

The benefits of fostering inclusivity extend beyond individual interactions. It raises awareness about the challenges faced by the deaf community and encourages advocacy for better accessibility in schools, workplaces, and public areas. As more people become equipped to communicate in sign language, we collectively work towards creating a society that values diversity and promotes equal opportunities for all.  Learning sign language is a great way to start.

3. Boosting Cognitive Skills

Research suggests that learning a new language—sign language included—can significantly boost cognitive abilities. Engaging with sign language challenges your brain in unique ways, requiring you to memorize signs, understand their grammar, and master a different modality of communication. This multifaceted approach enhances problem-solving skills and critical thinking.

Sign language involves a different grammatical structure than spoken languages, prompting learners to think creatively and flexibly. Studies have shown that being bilingual, including proficiency in sign language, can improve cognitive flexibility and executive function—skills that are valuable in everyday life and various professional settings.

Moreover, the visual nature of sign language makes it an engaging learning experience. As you visualize signs and associate them with meanings, you often find it easier to remember information. This can be particularly beneficial in both personal and professional contexts, enhancing your overall learning capabilities.

4. Bridging Cultural Gaps

Learning sign language opens the door to understanding and appreciating different cultures. Each sign language reflects the history, values, and social norms of its community, offering insights into the rich traditions and storytelling methods unique to the deaf culture. In short, each sign language has its own unique story

Engaging with the deaf community fosters empathy and understanding. When you learn sign language, you're not just learning a language; you're learning a whole new way of seeing the world. You'll gain a deeper understanding of different cultures and break down stereotypes along the way. This knowledge can help break down stereotypes and reduce biases, leading to more meaningful interactions across cultural lines.

In an increasingly globalized world, being able to navigate diverse cultural landscapes is more important than ever, more so invaluable. Learning sign language not only broadens your cultural horizons but also cultivates respect for different ways of communicating, building a bridge between different cultures, and fostering empathy and understanding.

5. Career Opportunities and Professional Growth

Imagine being able to communicate with anyone, regardless of their hearing ability. That's the power of sign language! In today’s world, knowing how to sign can give you a real edge.

In a workplace that’s becoming more and more diverse, having sign language skills can make you a valuable asset. Think about it—fields like education, healthcare, social work, and customer service all benefit from employees who can connect with deaf and hard-of-hearing individuals. It’s a skill that can set you apart in a competitive job market and open up some pretty unique opportunities.

Take teaching, for example. If you know sign language, you can create a classroom environment where everyone feels included, no matter their ability to hear. In healthcare, it’s even more impactful. Imagine being able to ensure that deaf patients understand their care and feel comfortable discussing their health concerns. Not only does this improve their overall experience, but it also helps build trust between patients and healthcare providers.

As businesses focus more on diversity and inclusion, the demand for employees who can communicate through sign language is only going to grow. You could be the one leading initiatives to make the workplace more inclusive and accessible, helping to create a positive work culture for everyone.

Communities and companies are realizing how important it is to have employees who can sign. These skills don’t just make a difference on a personal level—they can also lead to more inclusive projects and spaces. So, if you’re looking for a way to stand out in your career and make a real impact, learning sign language could be the game-changer you’ve been waiting for.
