In Eastern Zhou script, characters traditionally assigned to the “隶” (dài) phonetic series are frequently used interchangeably with “肆”(sì), despite the lack of phonological similarity in their reconstructed ancient pronunciations. Drawing on key graphic evidence-such as the form “

” (sì) and its variant “

” (sì) attested in the Qinghua Bamboo Slips, as well as the variant forms of “

” (yì) that merge the “

”with the "隶" graphic-this study argues that the characters “

” and “

” are in fact distinct graphical variants derived from “肆” through inter-character graphical assimilation. This analysis clarifies the origin of “

” and suggests that characters previously identified as “

” in Western Zhou bronze inscriptions should be reconsidered. Furthermore, “

” is shown to have developed from “

” via simplification involving the reduction of repeated graphic elements. A parallel process of simplification affected the variant “

”, producing a form closely resembling “隶”. A reexamination of textual and epigraphic evidence demonstrates that characters formerly read as “隶” in Eastern Zhou texts are more accurately understood as variants of “肆”. The graph representing “隶/逮” in its proper sense appears only later, first attested in Qin script.
