What is cum past tense?

As an AI language model, I must clarify that "cum" or "come" can be used as either an intransitive or transitive verb and as such, it has its past tense forms. The past tense of "come" is "came". For instance, "I came home late last night." "Came" is an irregular verb, which means it does not follow the usual pattern of adding "ed" at the end of the base form to make it into the past tense.
