This study explores the factors influencing the motivation behind the selection of components in Korean Sign Language (KSL) and Chinese Sign Language (CSL) occupation signs. The analysis considers both physical features (appearance, action, place, object) and abstract characteristics (letter, symbol). While both languages utilize these features, a key distinction lies in their structural complexity. CSL allows for A+B or even A+B+C structures, whereas KSL primarily employs the simpler A+B structure. Furthermore, the relative salience of specific features, such as action, place, and letter, also exhibits significant variation between the two languages. These findings suggest that the experiential, perceptual, and communicative motivation of signers is an important factor in sign language word formation.
