No, ‘fighted’ is not a word in standard English. The correct past tense of the verb ‘fight’ is ‘fought’.
In English, many verbs are irregular, meaning they do not follow the typical pattern of adding ‘ed’ to form the past tense. For example, the past tense of ‘go’ is ‘went’, and similarly, ‘fight’ changes to ‘fought’. Using ‘fighted’ would be considered incorrect in formal writing and speaking.
If you want to refer to the act of fighting that has already occurred, it is always best to use ‘fought’ to ensure clarity and correctness in your communication.
