口子

口子 refers to the mouth, the opening in the face used for speaking, eating, and breathing. It is a literal term, distinct from more abstract or metaphorical uses of 'mouth' in English.

The character 口 (kǒu) means 'mouth' or 'opening,' while 子 (zǐ) is a suffix often used to denote a small object or child. Together, they form a straightforward term for 'mouth,' emphasizing its physical nature.

口子 is commonly used in everyday speech and writing. It appears in phrases like 嘴角 (zuǐ jiǎo, 'corner of the mouth') or 口腔 (kǒu qiāng, 'oral cavity'). It is also used in more colloquial contexts, such as 挖口子 (wā kǒu zi, 'to create an opening' or 'to make a hole').
