The past tense of the verb ‘last’ is ‘lasted.’
When we talk about something that occurred in the past, we change the verb to reflect that time frame. The verb ‘last’ implies duration or continuation, and when we use it in a past context, we shift it to ‘lasted.’ For example, if you say, ‘The concert lasted for two hours,’ it clearly indicates that the duration of the concert is being referenced as a completed action in the past.
