Starting from a generic architecture for reading words in alphabetic scripts, we examine the special status of letters as the
building block of single word reading. After briefly describing the overall architecture that defines the interaction between
orthographic and phonological processes during silent reading for meaning, we then focus on orthographic processing. We describe
the nature of orthographic representations as hypothesized in our approach and we discuss how such representations might be
learned during reading acquisition. We present the hypothesis that such learning involves the adaptation of basic object
identification mechanisms to the specific constraints of reading, and we provide examples of this adaptation. In the light of
this, we then compare the function of letters as constituents of written words relative to the role of object parts in other kinds
of familiar visual stimuli (e.g. faces, numbers). We explain why we think letters must have a special status and we provide some
preliminary empirical evidence in favor of this special status for letters as parts of words. Keywords: reading; orthography;
visual word recognition; orthographic learning; letter strings; object identification
