A commonly used euphemism for ‘old’ is ‘seasoned.’ This term suggests that someone has had the time and experience to mature, much like food or spices that develop richer flavors over time.
The use of ‘seasoned’ brings a positive spin to aging, emphasizing wisdom and the valuable lessons that come with years rather than focusing solely on the decline that can accompany advanced age. Other euphemisms include ‘mature,’ ‘elder,’ and ‘vintage,’ each carrying connotations that celebrate the capabilities and perspectives that often accompany age.
