Commentary

The substitute ए replaces he last vowel, with the consonant that follows it, of the आत्मनेपद substitutes of that ल which has an indicatory ट्।
The ल or the tense-affixes that have an indicatory ट् are six:- लट्, लिट्, लुट्, लृट्, लोट्, लेट् । In these tenses the final portion called टि of the Atmanepada affixes is changed into ए । Thus त becomes ते, आताम् becomes आते, झ becomes झे &c, as shown in the foregoing table.

The affixes शानच्, and कानच् are also Atmanepada affixes. Why are not their finals changed into ए as in पचमानः, यजमानः? Because the word आत्मनेपदानां in the sutra refers by context to the Atmanepada affixes included in the Pratyahara तिङ् ।
