Sugar

Sugar derives from the Old French sucre and Medieval Latin succarum, ultimately from the Arabic sukkar and Persian shakar, tracing back to Sanskrit sharkara, meaning "grit" or "gravel" — referring to the granular texture of raw sugar. As a term of endearment, "sugar" has been used in American English for well over a century, carrying connotations of sweetness, indulgence, and affection.

Sugar ranks #155 among America's most popular pet names, sitting squarely in the category of endearment-names that owners choose to express pure affection. A pet named Sugar is, in the eyes of their owner, the sweetest thing in the room. The name has a particular warmth in the American South, where "sugar" as a term of address has deep cultural roots. It suits companions with a soft, gentle, irresistibly sweet personality — the ones who seem constitutionally incapable of doing anything wrong.
