口是嘴巴的意思，所以口字旁的字一般跟嘴巴、嘴巴的动作、嘴巴发出的声音（如啊、哦、嗯、咩、叽等拟声字）有关系。 但是说话等语言类的一般不用口字旁，而是用言字旁，因为言本身就是从嘴巴里面发出声音。
Mouth is the meaning of mouth, so the words next to the spoken word are generally related to the mouth, the movement of the mouth, and the sounds made by the mouth (such as onomatopoeia such as a , ó , èn , miē , jī, etc.). However, speaking and other languages generally do not use verbal words, but verbal words, because words themselves make sounds from the mouth.

钅[釒]作偏旁，称“金字旁”，很多简体是从草书中演变而来。比如讠[訁]、饣[飠]、纟[糹]、钅[釒]，在草书中就有写作今天的“钅”旁这种形式，所以带“釒”字旁的字就都用简体“钅”来表示了。
钅[釒] is used as a radical, called “Golden Words”. Many simplified forms are derived from cursive script. For example, 讠[訁], 饣[飠], 纟[糹], 钅[釒], in cursive script there is a form next to “钅” written today, so the words next to the word “釒” are all simplified “钅” to express.
