The affix añ comes after a word ending with tīra and the ñ comes after a word ending with kapya , in the remaining senses.,
This debars अण् ॥Thus काकतीरम्, पाल्वलतीरम्, वार्करूप्यम्, शैवरूप्यम् ॥ The words formed by अञ्, take the affix ङीप् in the feminine 4.1.15; those in ञ take the affix टाप् 4.1.4. The sutra is not enunciated as तीररूप्यान्तात्, for had it been so, the affix would apply to बहुरूप्य also, where रूप्य is final, but cannot be called uttara-pada, as 'bahu' is not a pada but is an affix 5.3.68. Therefore, we have बाहुरूप्यम् formed by अण् ॥,
