93. Certain other words

Certain other words also are, usually or always, without accent.

a. The particles ca, vā, u, sma, iva, cid, svid, ha, and the Vedic kam (or kám), gha, bhala, samaha, īm, sīm, are always without accent; also yathā in RV. (sometimes also elsewhere) in the sense of iva, at the end of a pāda or verse-division.

b. The same is true of certain pronouns and pronominal stems: mā, me, nāu, nas, tvā, te, vām, vas (491 b), ena (500), tva (503 b), sama (513 c).

c. The cases of the pronominal stem a are sometimes accented and sometimes accentless (502).

d. An accentless word is not allowed to stand at the beginning of a sentence; also not of a pāda or primary division of a verse; a pāda is, in all matters relating to accentuation, treated like an independent sentence.
