Attestation 3
Part of speech Noun phrase
Definition Acquired difficulty in spelling which can be divided into two groups: phonological agraphia and semantic agraphia.
Acquired difficulty in spelling words. These spellings disorders have been divided into two main groups: impairment of the nonlexical spelling route, that is an impairment of spelling via sound-to-letter correspondences, and disorders due to the loss of the ability to incorporate meaning into spelling (semantic agraphia).

Context Semantic (contextual) information is obviously required to select the appropriate spelling and Roeltgen et al.´s data show that the lexical system can be dissociated from semantic influence. Homophone substitution errors would then result from the (unguided) selection from alternative spellings. The foregoing has concerned spelling disorders. However, brain damage may also cause impairments to stages of processing which are implemented after a spelling representation has been either retrieved or assembled and deposited in the graphemic buffer (as shown in Figure 10.3).
