The word "揭谛" is formed through phonetic transliteration from the Sanskrit term "gate" in Buddhist mantras, where "揭" approximates the sound "jie" and "谛" approximates "di", with both characters being phono-semantic compounds, "揭" uses the hand radical "扌" and phonetic "曷", while "谛" uses the speech radical "讠" and phonetic "帝", but their semantic components are secondary to their phonetic roles in this construction.
