The word "吻戏" is formed by combining the character "吻", meaning "kiss", which itself is composed of the radical "口" (mouth) indicating its meaning and the component "勿" suggesting its pronunciation, with the character "戏", meaning "drama" or "play", composed of the radical "戈" (spear) relating to performance and phonetic elements. Together, "吻" specifies the action of kissing, and "戏" provides the theatrical or filmed context, resulting in the term for a kiss scene.
