唌唾（上祥延反俗字通用正體從水從欠作㳄說文口液也或從水作涎亦俗字也下土臥反釋准上從水垂聲也）。

Saliva and spittle (唌唾: the first character has the fanqie x- + [y]an [=xián]; it is a vulgar character commonly used; the standard form is composed of 'water' [水] and 'yawn' [欠] as 㳄; the Shuowen says: 'Mouth fluid'; or written with 'water' as 涎, which is also a vulgar character. The second character has the fanqie t- + [w]o [=tuò]; explained by analogy with the above, it is formed with 'water' and chuí [垂] as phonetic).
