she: [12] The Old English word for ‘she’ was hēo. As this evolved during the late Old English period, its main pronunciation stress shifted from the e to the o. The o gradually changed to an e sound, while the original e became transmuted into a y sound, which eventually merged with the h to form sh. The original h survives in her.

she (pron.)youdaoicibaDictYouDict
mid-12c., probably evolving from Old English seo, sio (accusative sie), fem. of demonstrative pronoun (masc. se) "the," from PIE root *so- "this, that" (see the). The Old English word for "she" was heo, hio, however by 13c. the pronunciation of this had converged by phonetic evolution with he "he," which apparently led to the fem. demonstrative pronoun being used in place of the pronoun (compare similar development in Dutch zij, German sie, Greek he, etc.). The original h- survives in her. A relic of the Old English pronoun is in Manchester-area dialectal oo "she." As a noun meaning "a female," she is attested from 1530s.
