The past tense of the verb ‘reach’ is ‘reached’.
In English, regular verbs such as ‘reach’ form their past tense by adding the suffix ‘-ed’ to the base form. Therefore, when you’re talking about a time in the past when someone managed to arrive at a place or achieve something, you would say they ‘reached’ it. For example, you might say, ‘Yesterday, I reached my destination.’ This structure helps in conveying that the action has been completed in the past.
