History & Origin

Cidney is a respelling of Sydney, which comes from an English surname and place name meaning 'wide island' or 'wide meadow'. As Sydney surged as a girls' name in the nineteen-nineties, spelling variants multiplied; Cidney is the C-initial form, keeping the sound and meaning while signaling a personal touch.

It crested near sixty girls a year around 1999, right at the height of the Sydney trend, then eased as the whole cluster cooled. A girl given it at its peak is now in her twenties, and it reads as a clearly datable turn-of-the-millennium variant.

Did you know? Cidney swaps Sydney's S for a C — one of many nineties respellings, like Cydney and Sydnee, that reworked a booming surname-name into a version families could call their own.
