“个”是汉语中最常见的一个量词，一般用于没有专用量词的名词前。例如：
"个" is the most common measure word in Chinese, usually used before a noun without a specific measure word of its own. For example:

• 三个老师
• 五个学生
• 一个杯子

“口”也是一个量词，一般用于描述家庭成员的人数。例如：
"口"is a measure word, too, usually used for members of a family. For example:

• 李老师家有六口人。
• 你家有几口人？
• 我家有三口人。

名量词重叠，常用“AA”格式，表示“每”的意思。名量词重叠后可做主语、主语的定语和状语，但不可做宾语和宾语的定语。
A noun or measure word is often reduplicated in the form of "AA" to mean "each, every". The head word modified by a reduplicated measure word can serve as the subject, the attribute of the subject or the adverbial, but not the object, nor the attribute of the object.
