We report on an Italian brain-damaged patient with impaired written spelling. The patient’s errors, in different fonts and scripts, consist mainly of letter substitutions (e.g., filo [thread] ® TILO). The results of various tests indicate that letter substitution errors arise because of a deficit in accessing the letter-form representations supporting written spelling. Letter substitutions occurred predominantly between letters with common strokes (e.g., C and G; b and p). Similarities in terms of global letter shape or letter sound were not valid predictors of letter substitution errors. Letter frequency, consonant–vowel status, and letter gemination were factors affecting letter substitution errors. The results of our investigation suggest that information about letter strokes are stored at the level of letter-form representations, and that access to these representations is sensitive to letter frequency. The results further indicate that letterform representations do not specify whether a letter is a consonant or a vowel, or is a geminate.
