Sanskrit Verb Conjugation: Path and Bhu Dhatu in Lat Lakar

Purush, vachan and lakar — the basics

A Sanskrit verb form depends on three things — पुरुष (person: प्रथम पुरुष = he/they, मध्यम पुरुष = you, उत्तम पुरुष = I/we), वचन (number: singular, dual, plural) and लकार (tense/mood, such as present, past, future). One dhatu in one lakar produces a total of 9 forms — three persons times three numbers.

The REET syllabus mainly covers five lakars — लट् (present tense), लङ् (simple past), लृट् (simple future), विधिलिङ् (should/possibility) and लोट् (command/permission). The basic person-ending framework for परस्मैपद forms stays the same across most dhatus, so once you understand one dhatu's लट् lakar well, forming the rest becomes much easier.

'पठ्' Dhatu Roop — Lat Lakar (present tense, parasmaipada)

पठ् belongs to the भ्वादि group; its pattern is the representative one for most ordinary परस्मैपदी dhatus such as गम्, पठ् and पत्.[Source 2]

'भू' Dhatu Roop — Lat Lakar (to be, parasmaipada)

'भू' (to be) is the most frequently used Sanskrit dhatu and is usually the very first one taught in any textbook.

Introducing the lakars: 'पठ्' dhatu's प्रथम पुरुष, एकवचन form in each lakar

For full exam readiness, memorise at least the प्रथम पुरुष एकवचन form of every lakar, then expand into a full 9-form table like the लट् one above. Always cross-check dual and plural forms against your textbook.

A structured way to memorise dhatu roop

The biggest challenge with dhatu roop is that one dhatu across five lakars can produce nine forms each — forty-five forms in total. So rather than trying to memorise all of it at once, break it into two stages — first get one dhatu's (say पठ्) लट् lakar completely solid, understanding its ending pattern (ति-तः-न्ति, सि-थः-थ, मि-वः-मः); then learn to apply that same framework to the remaining lakars (लङ्, लृट्, विधिलिङ्), since the underlying endings overlap quite a bit.

The second stage is applying the same method to another familiar dhatu (such as भू, गम्, पत्, हस्). The REET syllabus keeps returning to a fixed, small set of dhatus (पठ्, गम्, कृ, भू, दा, पा, हस्, वद् and similar), so focusing your effort on these is a genuinely time-saving strategy rather than trying to cover every dhatu in the language.

Practising dhatu roop inside sentences matters just as much as memorising the table. Sentences like 'बालकः पठति' (the boy reads), 'बालकौ पठतः' (both boys read) and 'बालकाः पठन्ति' (the boys read) shown side by side make it clear that as the subject's number changes, the verb's form has to change with it — this is the direct, practical link between शब्द रूप and धातु रूप.

In the REET paper, dhatu roop comes up both as a standalone question and hidden inside translation and sentence-construction questions, because no sentence is complete without the correct verb form. So it pays off far more to study dhatu roop alongside शब्द रूप, कारक-विभक्ति and अनुवाद कौशल than to memorise it in isolation.
