Usage remains recognizable across English-speaking countries through its connection to the more common Sydney.

Etymologically, the name comes from the English surname Sidney/Sydney. Scholars trace the surname either to Norman French Saint-Denis (via Sidney) or to an Old English place-name built from sīd “broad, wide” and īeg “island, river meadow,” yielding the meaning “broad island/meadow.” Variants include Sydney, Sidney, Sydnie, Sydnee, and Cydney; diminutives Syd and Syds are heard. Related but etymologically separate is French Sidonie. The celebrated Australian city Sydney, named for Viscount Sydney, helped keep the name familiar.
