The phrase describes the act of lifting and expanding bright light to a magnificent scale.

Origin

The phrase is formed by the characters 發, meaning to shoot or to launch; 揚, meaning to lift, raise, or hoist; 光, meaning light, beam, or ray; and 大, meaning of great size, big, large, or huge.

The character 光 is composed of the components 火, meaning fire or flame, and 卩, meaning a kneeling person. The character 光 is used with classifiers such as 束 or 道.

「發揚光大」由四個漢字組成。其中「發」的原意為射出或發射；「揚」意指舉起、抬高或吊起；「光」指的是光、光束或光線（量詞可用束或道）；「大」則表示巨大、大型或宏大。

在字形結構上，「光」字包含了「火」（火、火焰，量詞可用把或團）以及「卩」（跪者）這兩個組成部分。整個詞組透過這些字元的組合，用來表達推展與增進既有成果的含義。
