Concept:
In Sanskrit grammar,
Pratyayas (suffixes) are added to verbal roots (Dhātus) to derive different grammatical forms and meanings. Some suffixes indicate obligation, possibility, or necessity.
Step 1:Understanding the Tavya Pratyaya.}}
The suffix
Tavya (तव्य) is used to express the meaning of
necessity, obligation, or "should be done." It corresponds to the English sense of “must” or “should.”
Step 2:Example.}}
For example:
\[
कर्तव्यं = कर्तुम् अर्हति
\]
Here
कर्तव्यं (kartavyam) means {"that which should be done."}
Step 3:Distinguishing from other suffixes.}}
- Ktva – Indicates a completed action (“having done”)
- Tumun – Used to form infinitives (“to do”)
- Lyap – Used in gerund formations
Conclusion:
Therefore, the pratyaya used to express the potential or obligation meaning “should” is
Tavya.
