Written texts of Navajo and Western Apache speakers in English revealed rhetorical patterns which seem to be tied to the native languages. The theoretical framework of interlanguage is used to analyze language transfer of two rhetorical features at the discourse level: (1) rhetorical redundancy and (2) narrative technique. Both features can be viewed as fossilizations of discourse which are forced upon the surface of written Navajo and Western Apache English interlanguage by the process of language transfer.
