If "Venir"=to come, and "Volver"= come back, then what would be the correct way to express that someone "Came" as in past tense. For example: "He came to the airport". I assume it would be to conjugate PAST TENSE for the word "Venir", but just like "Tener" and "Ver" have slighly odd conjugations, I would assume that "Venir" does as well. Can you also please provide the PRESENT and PAST TENSE conjugations for "Venir". Thank you.
