From Young Sheldon Season two, episode three. Sheldon's mother, Mary, says
Stephanie Hanson's daughter was in a car accident last night. She died. Oh, no. My God. She was barely 16.
I guess "barely", "just" and "only" are interchangeable here and used to emphasize that girl was so young.
Is my understanding correct?
I can use this expression during the period of time that is after her 16-year-old birthday and before her 17-year-old birthday, right?
In other words, Suppose that girl was born at January 1, 2000. During the period of time that is after January 1, 2016
and before January 1, 2017
, I can say "She was barely 16".
Is my understanding correct?
