Commentary
The words राजसूय , सूर्य , मृषोद्य , रुच्य , कुप्य , कृष्ट , पच्य and अव्यथ्य irregularly formed by the addition of the affix क्यप्।
Thus राज्ञा सोतव्यः or राज्ञा इह सूयते, राज + सू + क्यप् = राजसूयः 'the Rajasuya or coronation sacrifice'.
Similarly सृ or सू + क्यप् = सूर्यः 'the sun', literally that which moves (सरति) in the sky; or that which impels (सुवति) creation to action. मृष +वद +क्यप् = मृषोद्यम् 'false speech'; this is an exception to rule 106, by which यत् would also have been applied This rule prevents it. Thus रोचतेऽसौ, रुच् + क्यप् = रुच्य. 'an agreeable lover'. So also गुप् + क्यप् = कुप्यम् 'a base metal (other than gold and silver)'; the other form is गोप्यम् । कृष्ट + पच् = कृष्टपच्याः 'that which ripens of itself in cultivated ground'. न व्यथते = अव्यथ्यः 'a snake (what does not move by legs)'.
