Assam Higher Secondary Skill Subject Sign Language cheat sheet

Sign languages are natural, fully developed languages with their own grammar, not signed versions of spoken languages; American Sign Language (ASL) and Indian Sign Language (ISL) are distinct systems with different vocabularies and structures.

ISL is used across India with substantial regional variation; there is no single monolithic 'Indian Sign Language', and vocabulary differences between regions can be significant.

Deafness is measured by hearing level in decibels (dB): mild 26-40 dB, moderate 41-55 dB, moderately severe 56-70 dB, severe 71-90 dB, profound 91 dB or above in the better ear.

'Deaf' (capital D) refers to cultural identity and shared language; 'deaf' (lowercase) refers to audiological status. 'Hard of hearing' denotes partial hearing use; 'Deaf-blind' denotes combined vision and hearing loss.

Around 90-95% of deaf children are born to hearing parents, so most deaf children acquire a sign language later than hearing children acquire speech, often on first contact with the Deaf community.

Manual-visual modality: sign languages use hands, face, and body in space; they are not pantomime and not universal - each country or region has its own signed language.

A sign has at least four parameters: handshape, location, movement, and palm orientation; non-manual features (facial expression, mouth pattern, head/body movement) form a fifth parameter.

Communication options include sign language, lipreading/speechreading, cued speech, total communication, oral-aural methods, and written communication; no single option suits every deaf person.

Legal and policy anchors in India: the Rights of Persons with Disabilities Act 2016 recognises deafness and speech-and-language disability and mandates accessibility; ISL received recognition momentum through national policy discussion and standardisation efforts.

Fingerspelling spells out words letter by letter using handshapes of the manual alphabet; it is used for proper nouns, technical terms, acronyms, and words with no established sign.

In ISL and most two-handed manual alphabets (including British Sign Language), the non-dominant hand acts as a base or chart and the dominant hand points to or contacts positions on it; ASL uses a one-handed alphabet.

Handshape accuracy matters: letters that differ only by finger contact or thumb position (for example, letters distinguished by thumb extension or by touching the palm) are the most common production errors.

Fingerspelling must be produced in a stable location, typically in front of the shoulder or upper chest on the dominant side, with the elbow relaxed and the hand not blocking the face.

Rhythm rule: produce letters in a smooth flow with a slight pause at word or morpheme boundaries; avoid letter-by-letter bouncing, which reduces legibility.

Reception strategy: read the whole handshape pattern and word shape rather than individual letters; fluent readers recognise clusters and predictable word endings.

Double letters are shown either by repeating the handshape with a small rebound or by sliding the handshape sideways, depending on the alphabet convention being taught.

Fingerspelled words can be lexicalised - a fingerspelled sequence becomes a fixed sign with its own reduced movement, as happens with many name signs and loanwords.

Practice targets: accuracy before speed; a common benchmark is a clear 1-2 letters per second for beginners, rising with fluency, with the non-dominant hand held steady.

Core everyday semantic fields to master first: greetings and leave-taking, self and family, numbers and time, food and drink, school and classroom objects, transport, health, emotions, and politeness formulas.

Signs are distinguished by minimal pairs: changing one parameter (handshape, location, movement, or orientation) changes meaning, for example signs differing only in movement direction or location on the body.

Name signs are assigned, not invented by the learner; a name sign typically encodes a personal characteristic or the initial letter of a written name and must be given by a Deaf community member.

Number signs follow systematic patterns; in ISL and many sign languages, numbers above a threshold combine a base handshape with movement or a second handshape rather than new arbitrary forms.

Time signs are often produced on or near the wrist or in a timeline in front of the body; tense can be marked lexically by time signs or grammatically by non-manual and movement markers.

Politeness and attention-getting: waving in the visual field, tapping the shoulder, or flashing lights are appropriate; shouting or grabbing are not.

Iconicity is helpful but unreliable: many signs are visually motivated, but learners must not guess meanings from appearance, since similar-looking signs can mean unrelated things.

Vocabulary learning should be paired with the sign's grammatical class, because the same handshape-movement pattern can function as noun and verb with movement or repetition differences.

Sign languages are not word-order copies of spoken languages; ISL and ASL use their own ordering, commonly topic-comment and subject-object-verb or object-subject-verb patterns depending on the construction.

Topicalisation moves the topic to the front of the sentence and marks it with a non-manual boundary, typically raised eyebrows and a slight head tilt or pause.

Yes/no questions are marked by raised eyebrows and a forward head tilt held across the question; wh-questions (who, what, where, when, why, how) use lowered eyebrows and a slight forward head position, with the wh-sign often at the end.

Negation can be lexical (a NOT sign), non-manual (headshake, frown), or both; in many sign languages the non-manual marker is obligatory and spreads over the negated clause.

Verb agreement: indicating verbs move between the signer's location (first person) and a location established for a referent (third person), so the path of the movement encodes subject and object.

Classifiers and depicting verbs use handshapes to represent categories of objects (vehicles, people, flat objects) and their movement or location to show action and spatial relations.

Referential space: a signer establishes a referent at a point in signing space and then points back to that location for pronouns and agreement; switching roles between characters uses body shifts.

Simultaneity: sign languages layer information - a manual sign can co-occur with a mouth morpheme, eyebrow position, and body lean, each contributing meaning.

Aspect and manner are shown by movement modulation: repeated, hold, or elliptical movement can mark habitual, continuative, or completed aspect rather than a separate auxiliary sign.

Reception is visual: maintain eye contact with the signer's face, not the hands, because grammatical information is carried by eyebrows, mouth, and head movement.

Peripheral vision handles handshape and location while central vision tracks the face; learners who stare at hands lose the non-manual grammar and misread questions as statements.

Turn-taking in signed conversation uses eye gaze, hand raise, shoulder touch, and holding the last sign; breaking eye contact is a turn-yielding signal.

Clarification strategies: repeat back what was understood, ask for repetition with a specific request (slower, again, fingerspell), and confirm meaning by paraphrasing.

Environmental factors: adequate lighting, plain background, no backlight, and unobstructed sightlines are prerequisites; masks and hands behind objects destroy legibility.

Comprehension repair: if a sign is unknown, ask for a fingerspelled version, a category clue, or an example rather than guessing from context alone.

Deaf conversational norms include directness, sustained eye contact, and rapid attention-getting; looking away while someone signs is equivalent to talking over them.

Interpreter-mediated conversation: address the deaf person directly in first person, not the interpreter, and allow processing time for the interpreted turn.

Storytelling in sign language uses constructed action and constructed dialogue: the signer shifts body position, gaze, and facial expression to portray characters rather than describing them from outside.

Role shift is marked by a head turn, shoulder shift, or eye-gaze change; returning to narrator position signals the end of the quoted segment.

Use of signing space for narrative: locations assigned to characters and objects must stay consistent across the story so the audience can track who does what to whom.

Pacing: hold key signs, use pauses and eyebrow raises for emphasis, and vary signing speed to build and release tension.

Classifiers carry much of the descriptive load in narrative - depicting the size, shape, path, and manner of movement of objects and people.

Facial expression is grammatical and affective at once: it marks clause type and negation while also conveying the narrator's stance and emotion.

Expressive fluency indicators: smooth transitions between role shifts, consistent referential space, accurate handshape holds, and rhythmic phrasing rather than isolated sign-by-sign production.

Audience design: adjust signing size, speed, and vocabulary to the receiver's level, and check comprehension visually rather than assuming understanding.

Non-manual features (NMFs) include eyebrow position, eye gaze, mouth morphemes, cheek and nose movement, head nod or shake, shoulder movement, and torso lean.

Eyebrow grammar: raised brows typically mark yes/no questions and topics; lowered brows typically mark wh-questions and negation in many sign languages.

Head movements carry meaning: a nod can mark affirmation or serve as a rhythmic clause boundary; a headshake negates; a head tilt can mark conditionals or contrast.

Mouth morphemes are meaningful mouth patterns that are part of the sign, not spoken-language lipreading; they can distinguish adjectival and adverbial intensity.

Adverbial NMFs modify the manual sign: for example, a particular lip and tongue pattern can mean 'carelessly' or 'effortlessly' across many different verbs.

Affective vs grammatical facial expression: affective expression shows emotion, while grammatical expression marks sentence type; both occur simultaneously and must not be suppressed.

Body orientation encodes participant roles and addressee: turning the torso toward a location addresses that referent.

Common learner errors: frozen or neutral face during signing, nodding while producing a negative statement, and using spoken-language mouthing that conflicts with the sign's meaning.

Deaf culture is a linguistic minority culture defined by shared sign language, shared experience, and endogamous social institutions such as deaf clubs, schools, associations, and deaf sports events.

Etiquette: gain attention by waving, tapping the shoulder, or flashing lights; do not shout, do not throw objects, and never physically force someone's head to face you.

Walking between two people who are signing is acceptable if you pass quickly and low; it is treated like stepping through a conversation rather than interrupting it.

Do not say 'hearing-impaired' or 'suffers from deafness' unless the person prefers it; 'deaf' and 'hard of hearing' are generally preferred, and 'Deaf' signals cultural identity.

Never ask a deaf person to speak or lipread on demand, and do not assume speech ability correlates with understanding.

Accessibility provisions: qualified sign language interpreters, real-time captioning (CART), visual alarms and doorbells, captioned media, and ISL interpretation in classrooms and public services.

Interpreter ethics: accuracy and completeness, confidentiality, impartiality, and role boundaries; interpreters do not advise, edit, or advocate for either party.

Communication access in exams and classrooms: extra time, interpreters, written instructions, and front-row seating with clear sightlines are standard accommodations, not favours.

Deaf Gain perspective: reframes deafness as a source of linguistic and cultural contribution rather than a deficit to be corrected.

Internal assessment typically combines continuous evaluation of signing performance with a portfolio and a practical demonstration; weightings are set by the board scheme of work, so verify the current year's circular.

Portfolio evidence types: signed video logs with dated entries, self-assessment sheets, vocabulary notebooks organised by semantic field, and reflections on Deaf community interaction.

Assessment rubrics usually score four dimensions: accuracy of parameters, fluency and rhythm, grammatical use of non-manual features, and communicative effectiveness.

Video evidence should be dated, labelled, and stored in a stable format (MP4) with clear framing that shows the full upper body and face; hands must never leave the frame.

A practical examination commonly requires a receptive task (comprehending signed questions), an expressive task (monologue or dialogue), and a fingerspelling task.

Self-assessment should reference the four parameters and NMFs explicitly rather than general impressions, so progress can be tracked across entries.

Recorded evidence must be the candidate's own work; collaboration on scripts is acceptable only where the scheme permits, and acknowledgement is required.

Portfolio progression: entries should show increasing vocabulary range, longer utterances, and reduced reliance on fingerspelling for common concepts over the course period.
