俱舍論記 2.32

2.32

「不爾二根至及莊嚴身」者，前師解。明根有用，顯所立因有不成過。謂舌能起言說用，鼻能莊嚴身用。

Regarding the passage: "Not so, the two faculties […] and for adorning the body," the previous master resolves it. He clarifies that the faculties have a use, showing that the reason established [by the opponent] suffers from the fault of being unproven (asiddha). That is, the tongue has the function of initiating speech, and the nose has the function of adorning the body.
