The word 诡谲 is formed by combining the characters 诡 and 谲, each containing the speech radical 讠, which indicates a relation to language or communication. 诡 incorporates the component 危, conveying danger or peril, thus suggesting deceptive or treacherous speech. 谲 includes the component 矞, associated with cunning or piercing, implying crafty or elusive speech. Together, they create a compound where both characters semantically reinforce the idea of deceitfulness, unpredictability, or mystery through their shared focus on deceptive verbal or behavioral qualities.
