Commentary
The तिङ् (Personal Endings) of the लिङ् (Benedictive) and the Potential take the augment स्युत् ।
The ट् of सीयुट् is indicatory and shows that this augment is to be placed before the affixes 1.1.46. The उ is for the sake of pronunciation; this rule applies to the Atmanepada affixes. In the Potential, the स् of this augment is elided by 7.2.79, and the य् also, before a personal-ending beginning with a consonant, is dropped according to 6.1.66. In this way, we have पचेत, पचेयाताम्, and by 3.4.105, पचेरन् । In the Benedictive, the augment retains its full form, only so far as it is not governed by 6.1.66. Thus पक्षीट, पक्षीयास्ताम् पक्षीरन् ।
