Origin note
Su/粟 is treated as an office-title surname with a later sound-change layer, not merely the grain word millet. One source-backed account derives it from officials such as Zhisu Neishi or Zhisu Duwei, whose duties involved grain, finance, or military supplies, with descendants using the office term. A second account says a Su/宿 branch was later written as Su/粟 by sound change. The page keeps those layers separate from the dictionary grain meaning.
