As part of a study of the feasibility and effect of teaching Navajo children to read their own language first, preliminary data on English loan words in the speech of 6-year-old Navajos were gathered in this study of the language of over 200 children. Taped interviews with these children were analyzed, and a spoken word count of all English words used was prepared. The document contains a discussion of English loan words that the children used and the light these words cast on linguistic acculturation; an appendix lists the English loan words according to semantic (subject matter/part of speech) classification; and a 138-page concordance of loan words, prepared by a computer program, provides an alphabetical listing of all words used by the children and interviewers and the sentence context in which the words occurred.
