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.
偏旁有”口”字旁的字与（口）有关。
举例如下：叨、吃、咬、叹、吵等等。
（1）叨 [tāo]承受：～光。～扰（谢人款待的话）。～陪。古同“饕”，贪。叨 [dāo]〔～～〕话多（后一个“叨”读轻声）。
（2）吃拼音：chī，是指用手或工具（筷子，叉子，勺子等）把食物送进口腔，经过牙齿咀嚼后下咽经食道管进入胃里，再由消化系统完成整个消化过程。
（3）咬，中国汉字，读音yǎo，交，交错，相互碰合。造字本义，上下前排牙相互交错合拢。表示上下牙对住，压碎或夹住东西。
（4）叹因忧闷悲痛而呼出长气：～气。～息。悲～。～惋。长吁短～。因高兴、兴奋、激动而发出长声：～赏。～服。赞～。
（5）吵声音杂乱，搅扰人，吵嚷。吵不是分贝大，而是产生噪音。例：别吵了，听杨老师讲话。争吵：吵嘴。例：别和小朋友吵。
以“口”为部首和字族的汉字多与发音说话有关。人和动物吃东西和发声的器官（亦称“嘴”） ：口腔。
