Fringe vocabulary

Personal detail makes communication specific

Fringe vocabulary can name family members, classmates, foods, places, characters, transit routes, body parts, diagnoses, medications, cultural events, favorite media, and technical interests. It lets someone say Grandma Elena, red line train, or migraine instead of relying on person, go, or hurt.

ASHA’s AAC portal describes fringe vocabulary as lower-frequency, often noun-heavy, and context-specific. It also emphasizes functional, personalized, culturally and linguistically relevant vocabulary.

Fringe and core solve different problems

Core words combine across many settings. Fringe words add exact content. A message such as “I want that” may work when the item is visible. “I want the astronomy atlas from my room” requires personal nouns and location terms.

A useful system includes both. A noun-only board can limit questions, refusals, descriptions, grammar, and novel messages. A core-only board can leave the person unable to name people, interests, health needs, or urgent details.

The communicator owns the vocabulary

Ask which words the person wants, how they spell or pronounce names, which identities matter, and which terms feel private. Avoid adding childish icons, clinical labels, or family judgments without involvement.

Vocabulary access does not authorize disclosure. A person may need a diagnosis or body word available for private healthcare while declining to show it at school or work. System design can use folders, access controls, or separate pages while preserving quick emergency communication.

Update language as life changes

People gain friends, jobs, classes, hobbies, relationships, medications, destinations, and jokes. Old terms can become inaccurate or unwelcome. Schedule easy vocabulary requests and regular review rather than waiting for frustration.

Fringe words support relationships and identity

Personal language lets someone greet a sibling by name, discuss a shared memory, use community slang, describe faith or culture, identify a favorite creator, and talk about attraction or gender in their own terms. These are central life topics even when the words are statistically rare.

Ask before adding photographs of people or private places. Confirm names, pronouns, and preferred images. A family member can suggest vocabulary, while the communicator’s choices and privacy remain primary.

Review those choices whenever relationships, names, or privacy preferences change.

Add language before a new event when possible. A museum trip, medical appointment, holiday, or job interview may need names, questions, navigation words, sensory messages, and an exit route. Keep useful words after the event when the person chooses.

Organization affects real access

Vocabulary exists only when the person can find and select it. Consider visual size, contrast, motor access, page depth, search, spelling, partner support, and consistency. A crowded temporary page can slow communication even when every desired word is technically present.

Avoid reorganizing the entire system for one activity. Preserve learned motor paths and add context-specific language in a predictable place with guidance from the AAC team.

A fictional museum example

Niko plans a model-train museum visit. He chooses 12 fringe items: three train classes, two station names, four exhibit terms, the café, his cousin’s name, and too crowded. Core words such as where, go, different, stop, and why remain available.

Before the visit, all 12 planned words are present and reachable in two selections or fewer. During the trip, Niko uses seven of them spontaneously and combines four with core words. He also spells one missing locomotive name.

Vocabulary readiness is 12 of 12. Spontaneous use is 7 of 12 planned words, which describes the sample rather than a required performance rate. Spelling the missing word reveals a system update, not an error by Niko.

Model possibilities and preserve authorship

Partners can model fringe words during real conversation and show how core and fringe combine. They should leave time, accept other communication modes, and avoid requiring imitation.

Physical support for positioning differs from selecting a message for the person. Do not assume that facilitated output is authored by the communicator. Record prompts and partner actions separately when measurement matters.

Protect continuous communication

ASHA states that AAC users should always have access to their tools or devices. Keep the system charged and available across settings, with a tested backup for repair, water, outdoor use, or travel. The backup needs important personal and emergency language too.

The BACB Ethics Code addresses competence, understandable communication, involvement, consent, assent when applicable, and collaboration for covered professionals. Behavior analysts should defer AAC-system design and language questions to appropriately qualified practitioners while contributing within scope.
