A Vocative, at the beginning of a sentence, is repeated, when envy, praise, anger, blame, or threat is meant by the speaker.,
A collocation of words, expressing one idea, is called a sentence or vakya. Thus (1) envy :- माणवका॑ ३ माणवक अ꣡भिरूपका॑ ३ अभिरूपक रिक्तं ते आभिरूप्यम् ॥ (2) praise - माणवका॑ ३ माणवक अ꣡भिरूपका॑ ३ अभिरूपक शोभनः खल्वसि ॥ (3) anger :- माणवका॑ ३ माणवक अ꣡विनीतका॑ ३ अविनीतक इदानीं ज्ञास्यसि जाल्म ॥ (4) blame :- श꣡क्तिके॑ ३ शक्तिके यष्टिके ३ यष्टिके रिक्ता ते शक्तिः ॥ (5) Threat - चौ꣡र चौरा꣡ ३ वृषल वृषला॑ ३ घातयिष्यामि त्वा, बन्धयिष्यामि त्वा ॥ The first word becomes pluta as well as gets svarita accent, by 8.2.103, in the case of the first four; in the case of 'threat', the second word or the amredita becomes pluta by 8.2.95. Why do we say \at the beginning of a sentence\? The Vocative in the middle or the end of a sentence is not to be repeated, as शोभन खल्वसि माणवकः ॥ Why do we say of a Vocative? Observe उदारोदेवदत्तः ॥ Why do we say 'when meaning envy &c'. Observe देवदत्त गामभ्याज शुक्लाम् ॥
In some books, the vakya is defined as 'a collocation of words having one finite verb', (एकतिङ् पदसमूहो वाक्यं) ॥ In the first example, कन् is added.,
