We report on a brain-injured subject, LAT, who made phonologically plausible errors in word spelling (e.g., "bouquet" spelled as BOUKET). Although many of his errors are phonologically plausible they contained low-frequency (yet lexically correct) spellings (/ei/ spelled as ET in BOUKET). Because these errors are phonologically plausible they do not appear to have been generated by the lexical process, yet because they contain low probability, lexically correct elements they do not appear to be have been generated by the sublexical process. We present analyses that specifically support the conclusion that many of LAT's phonologically plausible responses to word stimuli consist of the integrated output of elements generated by both the lexical and sublexical processes. This evidence constitutes strong support for the notion that lexical and sublexical processes share information during the course of spelling a familiar word.
