The production of a basic kindergarten through grade six word set, with accompanying linguistic data for use in the development of elementary communication skills instruction, is detailed in this report. Section one outlines the compilation of the 10,000 word lexicon, including a discussion of the form of the entries, the sources for the entry and general lexicons, and the empirical verification study. The second section describes the codes used with the lexicon to provide linguistic information, and the third section reports on the analysis of the linguistic information obtained through the codes. Numerous tables accompany the text. Appendixes contain a report of a new word study, pronunciation symbols and notational devices used in the report, three codes for spelling-to-sound correspondences, codes for prefixes and suffixes, bound bases, and six tables of frequencies of correspondences, affixes and epenthetic elements.
