One way of forming an intensive or frequentative stem in Sanskrit is to reduplicate the stem with the template CaCi-. Short i is used before any two consonants (kanikradat `roared', RV 5.83.9, from the root krand), long î before a single consonant (ganîganti `approach', RV 6.75.3) (Whitney 1889:364). Again the requirement must be for that syllable to be heavy, whether by being in a closed syllable or by having a long vowel. Since the first of any two consonant pairs is sufficient to close the syllable (giving ka-nik-ra-dat rather than the ka-ni-kra-dat that any OM theory would propose), the CS theory wins.
