Commentary
In a अङ्ग (stem) ending in न् the preceding vowel is lengthened before the affix नाम् ।
Thus पञ्चन् + नाम् 7.1.55 = पञ्चान् + माम् 6.4.7 = पञ्चानाम् 8.2.7; सप्तानाम्, नवानाम्, दशानाम् ॥ Why do we say 'ending in न्'? Observe चतुर्णाम् ॥ But not in चर्म्मणाम् where the affix is not नाम् but आम् without नुट् ॥
