The Vietnamese word "ổn định" is an adjective that means "stable" or "settled" in English. It is used to describe situations, conditions, or states that are not changing or are secure.
While "ổn định" primarily means stable, in certain contexts, it can also imply reliability or consistency. For example, when discussing a stable job or reliable income, you can also use "ổn định" to convey that sense of security.
