When you talk about things that happened before, whether recently or in the distant past, the word previously can be helpful. You could mention at a job interview that before your current job, you were previously employed as a flight attendant, or tell a date that though you're single now, you were previously married to a famous movie star. Previously comes from the adjective previous, with its Latin root praevius, "going before," from prae, "before," and via, "road."
