स्थानिवदादेशो ऽनल्विधौ ONPANINI 11056

A replacement is like the original, but not in a letter-rule.

Roughly reworded:

When a rule replaces something, the replacement inherits some characteristics of the original.

Example: rule GeryaH sometimes replaces /Ge with ya य. This /Ge is a /sup and has /Git. Then, according to sthAnivadAdezo स्थानिवदादेशो —

ya य is a /sup and has /Git.

Does it matter if ya य is a /sup or not?

Yes. Rule supica works only before /sup —

**rAma- रामॱ + /Ge → rAma राम + ya य by GeryaH → rAmA रामा + ya य by supica → **rAmAya रामाय

Why do we say "but not for a letter-rule"? What is a letter-rule?

Letter-rules are rules that depend on particular letters, not affixes. These rules "see" the letters of the replacement, not the letters of the original, ISO sthAnivad स्थानिवद्.

Example. Rules atoguNe and supica are letter-rules, because atoguNe works only before a अ e ए, supica only before bh भ् y य्. After GeryaH replaces /Ge with ya य, these rules "see" a ya य that is a /sup, like the original /Ge, and is /Git, like the original /Ge. But they can see nevertheless that ya य starts with y य्, not with e ए, like the original. And that is why atoguNe does not trigger while supica does.
