As ज्ञका, 7.3.47 कुमारिका, किशोरिका, ब्रह्मबन्धुका ॥ Why आ, ई and ऊ only? Observe गोका, नौका ॥ The words राका, धाका are irregular being formed by Unadi diversity, with the affix क added to रा and धा (Unadi Ill. 40). By the following sutra, the rule does not apply to the affix कप्; it therefore implies that कन् is governed by this rule, though it has the anubandha न् ॥ Katyayana would confine this rule to the Taddhita क, and not the krit क of the Unadi, as राका, धाका; but Unadi words are not derivatives (उणादयोऽव्युत्पन्नानि प्रातिपदिकानि), and hence no necessity of reading Taddhita into the sutra.,
