泡沫（上普包反下音末考聲云泡水上浮漚也沫水上浮沫也古今正字二字並從水包末皆聲之正字也）。

泡沫 (the first character is pu + bao fan; the second character is pronounced mo; the Kaosheng says: "泡 means bubbles floating on water; 沫 means foam floating on water"; the Gujin zhengzi states that both characters are correctly formed with 'water' [水] and have bao [包] and mo [末] respectively as their phonetic).
