What does linguistic competence encompass for an AAC user?

Linguistic competence for an AAC user pertains specifically to their understanding and ability to use the linguistic code utilized in their augmentative and alternative communication (AAC) system. This encompasses the vocabulary, grammar, and conventions that are part of the AAC system, allowing the user to effectively communicate messages in a meaningful way.

Having linguistic competence means that the AAC user is not only familiar with the symbols or language used in their communication device but also knows how to construct sentences, use appropriate phrases, and convey thoughts that reflect their intended meanings through the AAC system. This skill is crucial for engaging in conversation and interacting dynamically with others, as it supports effective communication beyond just the mechanical operation of the device.

Though knowledge of social interactions, ability to operate devices, and understanding of community practices are important aspects in a holistic view of communication, they do not specifically define the linguistic competence of the user within the context of AAC. Linguistic competence focuses directly on the framework of language itself that the AAC system employs.
