The "unknown past tense" in Nepali is commonly referred to as "अज्ञात भूतकाल" (Ajñāt Bhūtkāl). This tense is used to express past events where the specific time is unclear or unknown. It often implies that the speaker is uncertain about when the action occurred, or the emphasis is on the action itself rather than the time it took place.
The formation of this tense typically involves a root verb combined with gender and number agreement markers, followed by auxiliary verbs.
Note: The choice of auxiliary verb depends on the subject and context.
