Literally, "at another time"

ALIAS

Think of a word for a fake name that shares the same Latin roots as "alter."

The clue plays on the Latin phrase "alia" meaning "another" and "as" hinting at time—specifically, "at another time." While "alias" usually means a fake name, its literal roots break down to "at another time," which is exactly what the clue describes. It’s a straightforward etymology trick, where the answer’s original meaning matches the clue word-for-word instead of relying on its common usage.
