a different example of coronal harmony, sometimes referred to as "nati rule", occurs in sanskrit, where is retroflexed to if it is preceded by a retroflex continuant, mainly and , in the same word, even at a distance. the retroflexion spreads from left to right affecting any coronal nasal until the word boundary is reached. this phenomenon, however, is blocked whenever a coronal plosive is placed between / and . for instance, in the noun "brāhmaṇa" "brahmin priest" (derived from the root "*bṛh" "to make strong" + the suffix "-man-" + the thematic vowel "-a"), the original coronal (iast: "n") of the action noun suffix "-man" changes to a retroflex (iast: "ṇ") due to consonant harmony triggered by (iast: "r"). on the other hand, in the word अर्चन "arcana" "homage, praising" (from "*ṛc" "to praise" + "-man-" + "-a") consonant harmony is prevented by the coronal stop (iast: "c") which blocks the assimilation.
