Commentary

The affixes इनच् and पिटच् come in the sense of 'a hooked nose' after the word नि ; and चिक् and चि are the substitutes of नि before those affixes respectively.
Thus नि + इनच् = चिक् + इनच् = चिकिनः; नि + पिटच् = चि + पिटच् = चिपिटः ॥

Vart:- So also comes क, and चिक replacing नि, as नि + क = चिक् + क = चिल्लः ॥

Vart:- The affix ल comes after the word क्लिन्न in the sense of 'its eyes'; and चिल् and पिल् are substitutes of क्लिन्नः as, क्लिन्ने अस्य चक्षुषी = चिल्लः, पिल्लः 'blear-eyed'.

Vart:- चुल is also the substitute. As, चुल्लः ॥ These words apply to 'eye' also, as चिल्ले, पिल्ले, चुल्ले "sore-eyes." They apply to person also.
