परश् च

This is also an 'adhikara' or regulating sutra, and is understood in all subsequent aphorisms; or it might also be called a 'paribhasha' or interpreting aphorism. That which is called an affix comes after, or is placed after, the 'dhatu' or root, or the 'pratipadika' or crude form; as कर्त्तव्यम् and तैत्तिरीयम्.

The force of the word च 'and' in this sutra is to indicate that the affixes here treated of, are to be placed after a root &c.; not so, however the affixes, may sometimes, be placed in the beginning or the middle of a word.,
