Aphasia is a condition that may appear when parts of the brain (Broca's or Wernicke's area) responsible for language production and processing are damaged. In most cases, patients have the left side of their brain afected. Thus, formulaic language remains intact in most cases. During speech therapy, this can be a solid base to build on. Formulaic language consists of formulas that are ixed phrases, stereotypes that behave as a single-unit lexical item. They have a signiicant role in language acquisition and luent discourse production. These ready-made parts of speech are stored in the longterm memory. Studies suggest that the processing of formulaic language engages right hemisphere areas of the brain. Due to their language impairment, people with aphasia often have a lower quality of life, consequently social and professional integration for them being problematic. The investigation of preserved paterns, such as formulaic language and impairments related to diferent aspects of discourse, may provide insights both for clinical practice and for cognitive science, therefore, facilitating a more eicient approach to treatment.Conclusion: This comprehensive review assesses what we know so far about the use of formulaic language in aphasic speech to get a more complex view on how to beneit from this knowledge during evaluation and speech therapy to facilitate recovery. These indings may also have implications for future research.
