What does the name Sky mean?
Sky is a spelling of Skye, pronounced the same way, so it shares Skye's meaning and origin.
Skye is the name of the largest island of the Inner Hebrides in Scotland, Gaelic An t-Eilean Sgitheanach. Wiktionary notes that the island's name is of long-disputed origin, probably from a pre-Celtic language, with no theory widely accepted. As a girl's name it is a modern use of the place name or a fanciful spelling of the word sky.
An t-Eilean Sgitheanach (Scottish Gaelic, “the Isle of Skye (origin disputed)”)
How sure is this? Uncertain. The place name's origin is disputed; the given name may simply be the word sky.
