38. A method for spelling verification in a digital data processing apparatus, said method comprising the steps of A. inputting plural linguistic expressions, each said linguistic expression including alphanumeric characters, B. generating signals representing plural master lexicon entries, each said entry representing an input linguistic expression, C. forming plural master lexicon blocks, each said block being formed by the steps of (i) generating a linguistically salient word skeleton for each linguistic expression in the block, (ii) collating said block linguistically salient word skeletons and determining therefrom a block skeletal collation range, (iii) storing in a storage medium one or more master lexicon entries, D. forming a master lexicon wherein said blocks are arranged in an addressable sequence determined in accord with their respective skeletal collation ranges, E. inputting a signal representative of a suspect linguistic expression, F. matching said suspect expression with an expression represented in said master lexicon, and G. generating a signal indicative of the success of said matching step.
