This study explores the possibility of using phonemic synaesthesia as a source of evidence in phonology: if synaesthesia is sensitive to phonological units, it can serve as a diagnostic tool for phonological phenomena. Synaesthesia has been shown to be able to refer to acoustic properties and morphological units, which entails it has access to linguistic information. However, there is no similar research on the interaction of synaesthesia and phonology. The literature mentions the existence of phonemic (as opposed to graphemic) synaesthetes, which suggests that synaesthesia can make reference to phonemes: if /f/ is blue, that will be the colour for the coda segment of LAUGH lA:f, even though
