The recent past tense
Also known as: the aorist, bhūta (“past”), luṅ
Traditionally, the recent past tense refers to any past action regardless of time period:
अश्रौषम्
aśrauṣam
I heard.
But recall that Sanskrit has three past tenses. Since the ordinary past tense traditionally refers to non-recent (anadyatana, “not of today”) events, and since the distant past tense refers to distant (parokṣa, “unwitnessed”) events, only this tense can refer to very recent past events. That is why we call it the recent past tense.
The recent past tense often has the sense of having just done something:
अश्रौषम्
aśrauṣam
I have heard.
This tense is rare and complicated. Here, we will focus only on a few of its common patterns.
Making the stem
We make the stem of the recent past tense in many different patterns. Some roots use certain patterns, and other roots use other patterns.
Some roots are completely unchanged:
भू → अभूः
bhū → abhūḥ
become → you have become
Others use a connecting -a vowel:
गम् → अगमः
gam → agamaḥ
go → you have gone
A third group doubles in a special way:
नश् → अनीनशत्
naś → anīnaśat
perish, be destroyed → it has perished
A fourth group strengthens with the suffix -siṣ:
नम् → अनंसिषम्
nam → anaṃsiṣam
bow → I have bowed
A fifth group uses -sa:
श्रु → अश्रौषम्
śru → aśrauṣam
hear → I have heard
And there are other minor patterns, too.
Adding endings
Generally, these stems use the endings of the ordinary past tense.
The recent past tense without a-
Here is a common pattern worth knowing. We can use the forms of the recent past tense with a word like mā (“don't”) to state commands:
मा गमः।
mā gamaḥ.
Don't go.मा भैषीः।
mā bhaiṣīḥ.
Don't fear.
This command doesn't have any “past” meaning. It is just an alternate way of giving a command.
