accents Sandhi

if 2 vowels combine to form a long or diphthong

the latter has the udātta

if either or both of original vowels had it

nudasvātha nudasva atha

tavet tava it

kvet kva it

āgāt ā agat

piteva pitā iva

śato śatā u

nāntaras na antaras

i + i = ī

ousted the preceding udāta

divīva divi iva

when ī and ū with udāta are changed to y and v

the following unaccented vowel gets Svarita

vy ānaṭ vi ānat

when a is elided

it throws back its udātta on unaccented e or o

sūnave ‘gne sūnave agne

vo ‘vasaḥ vo avasaḥ

but

when unaccented a is elided,

it changes a preceding udātta to svarita

so ‘dhamaḥ so adhamaḥ
