The word 飞鹰 is formed by combining the character 飞, meaning "to fly" or "flying", which is a pictograph derived from the image of a bird with spread wings, with the character 鹰, meaning "eagle", a semantic-phonetic compound composed of the radical 鸟 indicating its category as a bird and the component 䧹 suggesting its pronunciation; together, they create a compound where 飞 modifies 鹰 to denote a "flying eagle", directly describing the eagle through its action.
