The Chinese word 孵化 (fūhuà), meaning "to hatch" or "incubate," is a compound formed by combining two meaningful characters: 孵, which specifically means "to brood or hatch eggs," itself a pictophonetic character composed of the radical 卵 (egg) and a phonetic component, and 化, which means "to change" or "transform." Together, they create a verb-noun or resultative compound where 孵 denotes the specific action related to eggs, and 化 signifies the process of transformation, thus literally conveying "to undergo the change of hatching." This formation exemplifies how Chinese often combines concrete action characters with abstract process characters to create precise terminology.
