止痛药 (zhǐtòngyào), meaning “painkiller,” is a three-character compound word where the meaning is derived from the combined meanings of its individual components. Let’s analyze each character:

止 (zhǐ):

• Early form: Depicted a foot.
• Original meaning: To stop, to halt, to cease.
• Evolution: While the connection to “foot” might seem unclear, some scholars suggest it originally conveyed the idea of stopping movement or coming to a standstill.

痛 (tòng):

• Early form: Showed a body with a tool or weapon piercing it, indicating injury or suffering.
• Original meaning: Pain, ache, suffering.
• Evolution: The visual representation of bodily harm clearly conveyed the concept of physical or emotional pain.

药 (yào):

• Early form: Combined the “grass/plants” radical (艸) with the component for “music/joy” (樂).
• Original meaning: Plants used for healing and harmony.
• Evolution: It evolved to encompass medicines and drugs used for treating illnesses.

Combining these, 止痛药 (zhǐtòngyào) creates a clear meaning:

• Medicine that stops pain: The characters “stop” (止), “pain” (痛), and “medicine” (药) literally translate to “stop-pain-medicine,” accurately describing the function of a painkiller.

This compound word effectively conveys the purpose of this type of medication: to alleviate or eliminate pain. It’s a straightforward and descriptive term.

It’s interesting how the word reflects a combination of stopping (止), a negative sensation (痛), and a healing solution (药).
