I also grew up in the previous century and it is equally strange to hear ‘dying by suicide’ when it used to be more common to say ‘committed suicide’ or just ‘killed himself/herself’. The author does a reasonable job of explaining why people might use ‘unalive’ and why he thinks that is a bad idea, but what was the reason a person started ‘dying by suicide’ instead of ‘killing himself/hersself/themselves’?
