81. The primary tones

The primary tones (svara) or accent-pitches are two: a higher (udātta raised), or acute; and a lower (anudātta not raised), or grave. A third (called svarita: a term of doubtful meaning) is always of secondary origin, being (when not enclitic: see below, 85) the result of actual combination of an acute vowel and a following grave vowel into one syllable. It is also uniformly defined as compound in pitch, a union of higher and lower tone within the limits of a single syllable. It is thus identical in physical character with the Greek and Latin circumflex, and fully entitled to be called by the same name.
