Weal is a noun that refers to well-being.

Our word of the day’s similarity to the word ‘wealth’ is no coincidence. Both have the same Old English origin and their meaning is related to well-being. But weal is a broader term that refers to a person’s best interest, while wealth usually pertains specifically to financial status.

For example: I was concerned about Melissa’s weal when she mentioned not getting much sleep lately. I get the feeling she hasn’t been doing very well.
