skys

Skys is a nonstandard plural form of the English noun sky. The standard plural is skies, created by replacing a final -y with -ies after a consonant, in line with general English spelling rules. The form skys is not accepted in modern standard writing and is usually considered a spelling error or an archaic/poetic variant.

History and usage: The spelling skys occasionally appears in older texts and in dialect writing, where orthographic conventions varied. In poetry or stylized prose, writers may deliberately retain 'y' spellings for rhyme or metre. Today, most style guides prefer skies and treat skys as incorrect in general prose.

Modern guidance: In formal or neutral writing, use skies as the plural. Spelling tools and dictionaries typically flag skys as incorrect, except when it appears as part of a proper noun or quoted material.

Other uses: When capitalized as Skys, the term may function as a proper noun, such as a surname or a brand name, independent of the ordinary plural form.
