Sinéad is French, Greek, Hebrew, Irish, Latin in Origin.
Sinéad is the Modern Irish form of Jane or Janet, shaped most directly from medieval French Jeannette, a diminutive of Jeanne. Its older line runs through Latin Iohanna and Greek Iōanna to Biblical Hebrew Yôḥānān, built from Yô-/Yeho-, referring to the God of Israel, and ḥānan, to be gracious. The literal sense is God is gracious. In Irish spelling, initial s before i is slender and pronounced /ʃ/, while é marks a long stressed vowel, giving shi-NAYD.
The name belongs to the Irish Gaelic revival of personal naming, when English Jane, Janet, and related forms were increasingly rendered in Irish. Sinéad de Valera, born Jane O'Flanagan, helped make the form visible in twentieth-century Ireland, and singer Sinéad O'Connor later carried it into international awareness. Related Celtic forms include Scottish Gaelic Seònaid and Welsh Sioned, while Sinead without the fada is common in English contexts.
