Commentary
Of a non-reduplicate root there is reduplication when the विकरण श्लु follows.
The श्लु is the characteristic sign of the roots of the third class, and causes the elision of the vikarana शप् ॥ The reduplication is of the first or second syllable, according as the root has an initial consonant or a vowel. Thus जुहोति (from हु), बिभेति, जिह्रेति ॥
