How to use it
'đã từng' combines the past marker 'đã' with 'từng' to clearly indicate someone has had a certain experience in the past. It does not mean all uses of 'already' but focuses on experience.
- More explicit than 'từng' in indicating past experience.
- Common in interviews, introductions, and talking about travel or work history.
- Not used for actions just completed once.
