Commentary

The finite verb retains its accent in connection with अङ्ग when used in a friendly assertion.
Anything done to injure another is prati-loma, opposite of this is apratiloma, or friendliness. In fact, it is equal to anuloma. Thus अङ्ग प꣡च 'yes, you may cook', Here anga has the force of friendly permission. So also अङ्ग प꣡ठ ॥ But when it has the force of pratiloma, we have:- अङ्ग कूजा꣡ ३ वृषल ॥ इदानीं ज्ञास्यसि जाल्म "Well, chuckle O sinner! soon wilt thou learn, O coward". Here अङ्ग is used in the sense of censure, for chuckling is a thing not liked by the person: and is pratiloma action: for pluta-vowel see 8.2.96.
