ทราย

From Proto-Southwestern Tai *zaːjᴬ (“sand”), from Proto-Tai *zwɯəjᴬ (“sand”), from Old Chinese 沙 (OC *sraːl, *sraːls, “sand”). Cognate with Lao ຊາຍ (sāi), Shan သၢႆး (sáay), Ahom 𑜏𑜩 (say) or 𑜏𑜩𑜤 (sayu), Zhuang saiz.

This word was written ซาย (saai) (with a ซ (sɔɔ) initial) in documents prior to the 18^th century, but shifted to the current spelling (with a cluster ทร initial) during the 18–19^th centuries, possibly under the popular misconception that this word was of Khmer origin, and that the s- initial had developed from an earlier *dr-.
