Sight word lists have been used since prior to 20 B.C. and have changed forms many times. Today sight word lists are numerous and are widely and variously used. They differ in source, intended purpose and/or audience, and criteria for including specific words. Despite the differences, there is much agreement that they do reflect the most basic words in our language and that there is a high degree of commonality among them. This report identifies the 100 sight words which appear in 16 major sight word lists, including "A Basic Word List from Basal Readers,""Gates Primary Reading Vocabulary," and "Thorndike-Lorge Reading Vocabulary."
