Features of Sign Language | Indian Sign Language (ISL) | Part 6

The manual alphabet (alfabeto manual) is the foundation for spelling words in sign language. When someone wants to spell a word, you use the letters A, B, C, and so on. This system allows deaf individuals to communicate by spelling out names and words letter by letter. The instructor emphasizes that this is the starting point for learning sign language communication.

Indian Sign Language (ISL) uses signs as its fundamental unit, similar to how English uses words and Hindi uses varn; learners must perform all signs within an imaginary box extending from head to chest, keeping signs in front of the chest (except for face-related signs) and avoiding simultaneous speech while signing; the alphabet consists of unique handshapes for each letter, such as E (three fingers left hand, one right), F (two fingers left, one right or two fingers overlapping), I (facing portion toward signer), J (thumb pointing inward with finger stroke), K (index finger loop), M (three fingers palm), N (two fingers palm), O, P, Q (hoop and hook), R (hook on palm), S (interlocked little fingers), T (both index fingers), U, V, W, X, Y (finger stroke), and Z.

This video provides beginner-level fingerspelling practice and a review of vocabulary from Lesson 01 and Lesson 02 of ASL University curriculum. It is part of a structured ASL learning series hosted on Lifeprint.com, a widely used online resource for learning American Sign Language and Deaf culture. The content is designed for learners beginning their ASL studies, focusing on foundational skills such as recognizing and producing manual letters of the ASL alphabet. The video is intended to reinforce early vocabulary introduced in the first two lessons of the ASL101 course. Dr. Bill, the instructor, is known for his clear, accessible instructional style and has developed extensive free online materials, including video lessons and reference pages for basic signs and fingerspelling. The video links to additional resources such as a dedicated fingerspelling tutorial (https://youtu.be/va1aAXpVr2w) and the full ASL101 lesson series at lifeprint.com/asl101. The video does not include detailed explanations of signs or grammar beyond what is implied by the lesson titles, nor does it describe specific vocabulary items or fingerspelling techniques beyond the general scope of beginner practice.

This comprehensive segment teaches the complete Indian Sign Language alphabet from A to Z. The instructor demonstrates each letter's hand configuration systematically: A (two fingers together), B (both hands together), C (three fingers on right chest), D (three fingers on right chest with index up), E (three fingers on right chest with index up), F (two fingers on right chest with index up), G (two fingers on both hands), H (right hand on left palm), I (left index finger pointing at face), J (left index at face, right index draws upward), K (both index fingers in circle), L (left palm forward, right index draws upward), M (left palm flat, three fingers on top), N (two fingers on left palm), O (both hands form cup with right index on top), P (left palm flat, right index forms cup), Q (both hands form cup with right index on top), R (left palm flat, right index forms cup), S (two small fingers together), T (left palm flat, three fingers on top), U (two fingers on left palm), V (both hands form cup), W (four fingers crossed), X (fingers crossed), Y (left hand flat, right hand draws upward like brush), Z (left hand flat, right hand draws upward like brush).

Manual alphabet refers to fingerspelling where letters are signed using hand movements. India uses more than 40 manual alphabets globally, but only two types are common in Indian Sign Language (ISL): double-handed and single-handed alphabets. The double-handed alphabet, borrowed from British Sign Language, is more commonly used in ISL. The single-handed alphabet, derived from American Sign Language, is less frequently used but serves important practical purposes. This lesson teaches the single-handed alphabet from A to Z, providing learners with an alternative signing method that offers flexibility in various communication situations.

Oral-auditory languages use voice through speech as emission and ears through hearing as reception, with vision supporting comprehension through lip reading. Children learn oral language first through listening, then later learn writing through formal schooling. Visual-spatial languages like Libras use hands through signs as emission and eyes through vision as reception. Libras is an agrapha language without standardized written form, using video for systematization. This fundamental difference in communication modality creates distinct learning processes: deaf children learn sign language first through visual observation, then later learn written language, mirroring the oral-auditory sequence but in reverse order.

Modalidade refers to how language is expressed and received. In Libras (sign language), modality is visual and spatial: information is transmitted through hand movements in a neutral space in front of the body and received through vision. In oral languages, modality is oral and auditory: information is transmitted through voice and received through hearing. The key difference lies in the transmission and reception channels, not in the cognitive decoding process, which occurs identically in the brain for both modalities. This concept is fundamental for understanding how sign languages function as complete linguistic systems.

Visual languages are systems used for drawing, analogous to spoken languages for speaking. They use the same types of linguistic structure: a visual vocabulary built of memorized units stored in memory (both fixed and productive items), ordered by a grammatical system using grammatical roles and hierarchical constituents. There is cross-cultural diversity in visual languages corresponding to different drawing systems. The language faculty is actually a multimodal faculty consisting of three inherent modalities: graphic (visual), vocal (speech), and bodily (gestures). This architecture includes correspondences between modalities—for example, writing creates a correspondence between vocal sounds and graphic representations. Expressions emerge as interactive activation states of the subcomponents within this broader architecture.

This segment continues reviewing signs including 'Auxiliar' (to assist), 'Interpretar' (to interpret), 'Pós-graduação' (post-graduation), 'Capaz' (capable), 'Preparar' (to prepare), 'Pronto' (ready), and 'Acabou' (finished). The instructor explains that these signs are used in different contexts and have different meanings depending on the situation. The instructor emphasizes that Libras is a visual-spatial language that 'shows' stories, while Portuguese is an oral-auditory language that 'tells' stories. This fundamental difference means that Libras uses visual and spatial elements including facial expressions and body language. The instructor explains that artificial intelligence cannot effectively translate between Libras and Portuguese because the communication channels are fundamentally different.

Language encompasses three basic types: visual (images, drawings), written, and spoken. Language is everything that enables production, development, and comprehension of communication. Language (língua) is an organized system of sounds and gestures enabling communication, with each country having its own language (e.g., Libras as Brazil's second official language). Verbal language uses words through writing or speech, while non-verbal language uses symbols, colors, images, gestures, tone, and posture. Mixed language combines verbal and non-verbal elements in the same communication.

Deaf culture has distinct etiquette rules including methods to get attention (looking at face, tapping shoulder, waving, thumping table), turn-taking signals (holding last sign and looking away), and communication norms where getting as much information as possible is normal, unlike hearing culture which is more formal and secretive; key differences include informal initial interactions, lengthy conversations, and openness about personal information.

Deaf culture is a unique culture with shared values, beliefs, and American Sign Language. Etiquette points: (1) Speak directly to the deaf person, not their interpreter, (2) Ask how they prefer to communicate, (3) Written communication may take longer to decipher because English is not their primary language, (4) Avoid shouting at deaf people, (5) The term 'hearing impaired' is becoming outdated. Effective communication strategies: give full attention, don't interrupt, ask calmly to repeat if needed, repeat what you heard, consider quieter environments, and ask what they might need.

Deaf culture has specific communication etiquette, including using hand applause instead of verbal applause. Anna Hasland explained that after her story, the audience should show respect by raising their hands for applause, which is customary in deaf culture. This illustrates the importance of understanding and respecting cultural communication differences in social settings.

When communicating with deaf individuals, gaining their attention is crucial. Simply shouting loudly is ineffective if they cannot see your face. The proper approach is to gently tap their shoulder to get their attention. Maintaining eye contact is essential because deaf individuals rely on visual cues to understand what is being said. Facial expressions and body language are crucial components of sign language communication. When communicating with deaf individuals, the hearing person should use clear facial expressions to convey emotions and meaning. Indian Sign Language includes specific hand gestures for common greetings: 'Hello' (हाय), 'Hi' (ही), 'Namaste' (नमस्ते), 'Good Morning' (गुड मॉर्निंग), 'Good Evening' (गुड इवनिंग), 'Thank You' (थैंक यू), 'Welcome' (वेलकम), 'Good Night' (गुड नाइट), 'Nice to meet you' (नाइस टू मीट यू), 'Sorry' (सॉरी), 'Congratulations' (कांग्रेचुलेशन), 'Please' (प्लीज), 'Take care' (टेक केयर), 'Have a good day' (हैव अ गुड डे), 'Goodbye' (गुड बाय), 'See you again' (सी यू अगेन), 'Happy Birthday' (हैप्पी बर्थडे), 'Well done' (वेल डन), 'Thank you for your help' (थैंक यू फॉर योर हेल्प), 'I am sorry for this mistake' (आई एम सॉरी फॉर दिस मिस्टेक), 'Your signing skill is excellent' (योर साइनिंग स्किल इज एक्सीलेंट), 'Take care of your health' (प्लीज टेक केयर ऑफ योर हेल्थ), 'Go ahead' (प्लीज गो अहेड), 'Congratulations on your success' (कांग्रेचुलेशन ऑन योर सफलता).

Deaf culture is a distinct cultural identity with its own traditions and communication methods, and Indian Sign Language (ISL) uses hand movements, facial expressions, and body language to convey meaning, with clear signs being essential for effective communication, especially when spelling words or alphabets.
