古玉
gǔ​yù

ancient jade

古 gǔ old

Original meaning: firm, solid

Depicts a shield. Based on the original meaning "firm, solid", which is now written as 固. The current meaning "old" is a phonetic loan.

Components

盾 Iconic component
dùn shield

Change in form
Due to historical stylistic changes, this component is less similar to 盾 than it was in ancient scripts.
口

The 口 component is sometimes used to indicate an abstract meaning taken from a concrete object. Here, the concrete object "shield" evokes the abstract meaning "firm, solid".
