飲吮（旋兖反集訓云吮口嗍也說文吮欶也從口允聲論作𠵷非也或作冤）。

Drinking and sucking (飲吮: [吮 is pronounced] xuan-yan fan; the Jixun says: "吮 means sucking with the mouth." The Shuowen says: "吮 means to suck; it takes 口 as semantic and 允 as phonetic." In the treatise it is written as 𠵷, which is incorrect; it is also written as 冤).
