The affix yan is added in the sense of 'collection thereof' after the words 1. brāhmaṇa 2. māṇava and vāḍava ,
The indicatory न् of यन् makes the word take udatta accent on the first syllable (VI. I. 197). Thus ब्राह्मण्यम्, माणव्यम्, वाडव्यम् ॥
Vart:- Also after the word पृष्ठ e.g. पृष्ठ्यः ॥
Vart:- The affix ख is added to अहन्, in the sense of a 'sacrifice'. e.g. अहीनः 'a collection of days of sacrifice'. Otherwise the form is आह्नः by अञ् see 4.2.45.
Vart:-The affix णस् comes after पर्शु, e.g. पार्श्वम् 'a collection of axes'. The final उ of पर्शु is not changed by guna into ओ before the affix, because the word पर्शु is treated as a pada-word (1. 4. 16) and not a Bha-word.
Vart:- The affix ऊल is added to वात e.g. वातूलः 'a collection of winds or a mad-man'.,
