The future tense of ‘come’ is ‘will come’.
In English, the future tense is typically formed by using the modal verb ‘will’ followed by the base form of the main verb. In this case, ‘come’ is the base form. So when we want to indicate that someone or something will arrive at a place in the future, we use ‘will come’.
For example, you might say, ‘They will come to the party tomorrow.’ This sentence indicates that their arrival at the party is expected to happen in the future.
