Commentary
Before the affixes इष्ठन् and इयसुन् , कन् is optionally substituted for युवन् and अल्प।
Thus कनिष्ठः, कनीयान् or यविष्ठः, यवीयान्; similarly अल्पिष्ठ, अल्पीयान्, or कनिष्ठः, कनीयान् ॥ सर्वइमे युवानः, अयमेषामतिशयेन, कनिष्ठः । द्वाविमौ युवानौ अयमनयोरतिशयेन, कनीयान् । यविष्टः । यवीयान् । सर्वइमेऽल्पाः । अयमेषामतिशयेन, कनिष्ठः । उभाविमावल्पावयमनयोरतिशयेन कनीयान् । अयमस्मात्कनीयान् । अल्पिष्ठः अल्पीयानिति वा ॥
