Construction of Verbs by Conjugation using Roots from the Dhatupatha is one of the most complex and involved processes in Sanskrit Grammar. It has been coded by the great grammarian Panini in a beautifully amazing way through the core texts, viz. The Dathupatha of Panini, The Ashtadhyayi of Panini and The Maheswar Sutras. This book hopes to lay the coding methodology threadbare in a lucid manner for avid learners of the language, including Sanskrit scholars and Vyakarana pundits.

Root + Vikarana Affix + Ting Affix = Verb, where
Roots have two major attributes, i. P A U attribute ii. सेट् अनिट् वेट् attribute.
Vikarana affixes are of two types, i. Gana Vikarana Affix and ii. Vikarana Affix.
A Vikarana Affix may be Sarvadhatuka or Ardhadhatuka. This affects Guna/Vriddhi.
Ting affixes are of two types, i. Parasmaipada Ting Affix and ii. Atmanepada Ting Affix.
Further, a Parasmaipada Ting Affix may be Sarvadhatuka or Ardhadhatuka. Similarly, an Atmanepada Ting Affix may be Sarvadhatuka or Ardhadhatuka. This affects Guna/Vriddhi.
A Sarvadhatuka Ting Affix is of two types, पित् or अपित् that also affects Guna/Vriddhi.

Notes:
Any affix whether Vikarana or Ting is further of two types, i. Consonant beginning or ii. Vowel beginning.
Additionally, Affix modifiers may also be employed.
Similarly, Root modifiers may also be employed.
Each Root may have a Tag Letter, that is simply a marker to serve a specific purpose and then gets dropped.
Each Affix may have a Tag Letter, that is simply a marker to serve a specific purpose and then gets dropped.
Dropping or Elision of certain parts of Root or Affix in certain cases.

Of utmost importance is understanding that the Tenses and Moods in Sanskrit Grammar (Present Tense, Past Tense, etc.) are coded in terminations known as Ting Affixes. These Ting Affixes are of two basic types: Parasmaipada and Atmanepada, and these will only join a Root having the same attribute of Parasmaipada or Atmanepada.
The Ubhayepada Ting Affixes are simply a combination of the two, so Roots that are Ubhayepada will invariably be grouped under Parasmaipada and Atmanepada both.

Major Concepts include:
-The Ten Tenses and Moods that reflect the Verb usage.
-Grouping of Roots in ten Ganas for Sarvadhatuka Ting Affixes.
-Tag Letters and their interpretation.
-Guna/Vriddhi of Vowels (whether of a Root or an Affix).
-Use of इट् augment.
-Correct use of Sarvadhatuka/Ardhadhatuka Affixes.

This books has been designed to look at all these grammatical concepts from the Root-point-of-View. It contains exhaustive lists of Roots that behave in a specific manner during Verb construction.

Indexes and collections are based on the Dhatu Serial Number, which is unique and easily referenced in standard Dhatupathas, including Siddhanta Kaumudi. Hence locating any Root is a snap.

So this book will primarily be used as a supplemental text for any standard text on Sanskrit Grammar. On its own also it can prove to be immensely useful if one wishes to master the Dhatupatha of Panini.
