Passive Verbs
Recall that the gerund is a verb form that depends on the roots's spelling instead of the root's verb class. Here, we will study another sort of verb that does the same.
Introduction
Consider the two sentences below. What is the difference between them?
I remember the man.
The man is remembered.
There's no subject in the second sentence! We do not know who or what the subject is. It could be "I," it could be "Arjuna" — it could even be "the two horses" for all we know! Such a sentence is called a passive sentence because it does not clearly state the subject of the sentence. In fact, the subject is optional; we are not required to supply it, although we can do so anyway.
The man is remembered by me.
Passive verbs in Sanskrit
Passive verbs are very common in Sanskrit, and it is nearly impossible to find a text that does not use passive verbs of some kind or another. Since passive verbs are formed straight from a verb's root — with no reference to a verb's class — we can study verbs from unfamiliar verb classes with no problems.
We can translate all three of the example sentences above into Sanskrit:
अहं नरं स्मरामि
ahaṃ naraṃ smarāmi
I remember the man.
नरः स्मर्यते
naraḥ smaryate
The man is remembered.
नरो मया स्मर्यते
naro mayā smaryate
The man is remembered by me.
Here, we can imagine that the first sentence is the original one. Then, the shift from a non-passive verb to a passive verb becomes straightforward:
- The old object (case 2) becomes the subject (case 1).
- The old subject (case 1) becomes the means of the verb (case 3). Note that this noun is optional.
parasmaipada and ātmanepada
Regardless of whether the original root is a parasmaipada verb or an ātmanepada verb, the passive verb has the same meaning. ātmanepada verbs do not become passive as often as parasmaipada verbs, but they still follow the pattern:
लभ् → लभ्यते
labh → labhyate
obtain → It is obtained.
In Proto-Indo-European, passive verbs were a sub-type of the ātmanepada verbs. For that reason, the two are lumped together today as the mediopassive verbs. Here, "medio-" refers to the "middle voice," which is the English term for ātmanepada and its counterpart in other languages.
Formation
Passive verbs always use ātmanepada endings. To form the passive stem, we add ya to the end of the root; that is, we treat the root like a ya-class ātmanepada verb. As with the gerund, roots appear in a weakened form. Samprasarana roots will weaken accordingly.
वच् → उच्यते
vac → ucyate
say, call → it is called
Now, here are some more general changes.
Roots ending in vowels
Final ā becomes ī.
स्था → स्थीयते
sthā → sthīyate
stand, establish → It is established.
Final i and u become long.
जि → जीयते
ji → jīyate
conquer → It is conquered.
After just one consonant, final ṛ becomes ri. Otherwise, final ṛ becomes ar.
कृ → क्रियते
kṛ → kriyate
do → It is done.
स्मर् → स्मृ → स्मर्यते
smṛ → smaryate
remember → It is remembered.
Final ṝ changes according to the rule we discussed in the lesson on gerunds.
तर् → तॄ → तीर्यते
tṝ → tīryate
cross → It is crossed.
पॄ → पूर्यते
pṝ → pūryate
fill → It is filled.
As always, try pronouncing these words without the sandhi changes applied. By doing so, you can better understand the reasons for the changes above. The first change (e.g. sthā → sthīyate), however, is irregular.
Roots ending in consonants
Generally, no changes occur.
