Sid is primarily a diminutive of Sidney, a surname derived from a place name. The etymology of Sidney is debated: it may come from Old English 'sīd' (wide) + 'īeg' (island), or from the French place name Saint-Denis. As a given name, Sidney gained popularity in the 19th century, and Sid emerged as a common nickname by the 20th century.
