What does 嘴 mean?
嘴 (zuǐ) is the noun for 'mouth' on a person or animal, and by extension the spout-like opening on objects (茶壶嘴 teapot spout, 瓶嘴 bottle neck). It is the everyday body-part word that natives reach for when talking about eating, kissing, talking, or pouting. Two contrasts with English help: first, Chinese distinguishes 嘴 (the physical mouth, lips and all) from 口 (kǒu, the mouth as an opening, used in formal, medical, and idiomatic contexts like 人口 population or 口语 spoken language) — English collapses both into 'mouth.'
Second, 嘴 often carries personality: 嘴甜 'sweet-mouthed' means good with flattering words, 嘴硬 'hard-mouthed' means stubborn in argument. The word is concrete and warm; 口 is abstract and formal.
Note: 嘴 is the everyday word for mouth on a person or animal. In medical or anatomical contexts, 口 (kǒu) is preferred (e.g. 口腔 oral cavity); in poetry or formal description, 口
Character breakdown
mouth; the 口 radical on the left signals 'mouth'; the right side 觜 gives the sound
Memory hook: 口 (mouth radical) on the left tells you it's about the mouth — the rest of the character is just the sound.

Synonyms

Don't confuse 嘴 with
咀 means 'to chew' and appears in 咀嚼 (jǔjué, to chew). It looks like 嘴 but the right side is 且 not 觜, and the meaning is the action, not the body part.
