The Recent past tense refers to some action that happened a day or two ago.
I just heard.
However, the difference between the ordinary present tense and the recent past tense is not quite clear yet. Different schools and communities of Sanskrit use their own way of distinguishing the difference. The main problem is that there is no parameter to measure the nearness of the verb.
Some examples of the stems of the recent past tense are given below;
|Root||None||bhū → bhū|
|Vowel||None||gam → gama|
|Doubled||None||naś → nīnaśa|
|sa||Strong||śru → śrauṣ|
|Sis||hā → hāsiṣ|
|si||Strong||bhī → bhaiṣī|
Past tense without –a prefix
Interestingly, when the a sound is removed from the verbs in ordinary and recent past tense it describes the words as “wishes” and “desires”. They more commonly appear in Vedas and other mythological scriptures and are used to give strong commands. The words used for this purpose is “ma”, “smā” which means “do not ever”
