Telegraphic Speech Also called agrammatism. When a speaker omits grammatical structures with function words, such as articles, auxiliary verbs, and prepositions. As a result, utterances are incomplete and resemble the short messages sent in telegrams in which only main content words are used to share the gist of the message to reduce telegram costs. Example Mommy here, mommy here for a child who is excited that his Mommy is here. This is a symptom of expressive aphasia (or Broca’s aphasia).

Total Communication Abbreviated TC, this communication method is a philosophy about the way people with hearing loss communicate with others. In this view, from a young age, children with hearing loss are taught to communicate using all means available to them, including formal sign language (like American Sign Language, or ASL), gestures, body language, lip reading, listening and spoken language (like Auditory-Verbal Therapy). In comparison to a single method, like ASL, TC focuses on auditory, verbal, tactile, and visual modalities of communication.

Transcortical Aphasia A group of three types of aphasia in which repetition skills remain intact, despite impairment in other language areas. For example, a patient may have significant difficulty speaking, but he or she is able to repeat words and phrases with ease.

  • Transcortical Sensory: A fluent aphasia, similar to Wernicke’s aphasia, but the patient is able to easily repeat words and phrases despite poor language comprehension.
  • Transcortical Motor: A nonfluent aphasia, similar to Broca’s aphasia, with impaired expressive communication; however, the patient is able to easily repeat words and phrases despite difficulty with verbal expression.
  • Mixed Transcortical: A combination of both fluent and nonfluent aphasia in which both receptive and expressive language skills are impaired, but the patient has strong repetition skills.
