The Merriam-Webster Dictionary defines the term family as "a social group made up of parents and their children." So it's my understanding that this would include me, my parents and any siblings. However, some people say "you and your family" as if they're two separate entities. The examples I see the most often are "I wish you and your family all the best" and "deepest condolences to you and your family."
So does the term family include that person themselves? In other words, is the phrase "you and your family" redundant?
