The Third Conditional in Nepali grammar talks about a situation that didn’t happen in the past and the result that could have followed it. This typically involves the use of the past perfect and the conditional perfect tense. In Nepali, this can be seen through the use of words like भए (harma), would have (थिएन।) which signifies the event’s non-occurrence. The Third Conditional helps to discuss hypothetical scenarios and their unrealized outcomes.
