ल्यप् प्रत्यय / lyap pratyaya (Sense Of Preceeding Action): In this chapter we will study the ल्यप् प्रत्यय (lyap pratyaya). This verb form is used for the same purpose as क्त्वाच् प्रत्यय (ktvaach pratyaya). In other words this represents the verb form to express - an action which preceeds another action. However, it is used only if the verb is prefixed with any preposition or उपसर्ग (upasarga) like प्र (pra), आ (aa), उप (upa), परा (paraa), सम् (sam), नि (ni), अभि (abhi), निः (niH), वि (vi), अधि (adhi), निर् (nir), उत् (ut), परि (pari), अनु (anu) etc. In this the verb root gets the ल्यप् (lyap) suffix. Study the following sentences. These are using ल्यप् प्रत्यय (lyap pratyaya).
In setences 1 to 11 there are two actions, one following the other. The verbs "come", "read", "refer", "enter", "collect", and "go near" are suffixed with ल्यप् प्रत्यय (lyap pratyaya), as these represent the action preceeding the other action, and are prefixed with prepositions (उपसर्ग / upasarga).
