I have a question about the the usage of words.
If a word has a particular meaning in a specific context that contradicts, ignores or stretches beyond the way that word is used in more general context, is that word being used wrong?
For instance, consider the term "game." I've frequently come across arguments in different spheres about what constitutes a "game" and how such-and-such use of the term is mistaken. In some contexts a "game" can be all sorts of things (consider the bewildering variety of video games that have almost nothing in common with one another), in others it must be something competitive (there are people who express hesitation at calling solitaire a true "game"), in other contexts "games" need to have a structure of some kind or another (some say that children's imaginative games are not games, but merely "play" in a vague sense).
My question is, if certain contexts use a term in a certain way, one that deviates from the understanding of that term in broader contexts, are those contexts making incorrect use of the term? Is it legitimate to say "When we talk about games we usually mean X, so saying that Y is a game is wrong." even if Y is frequently considered a game within the specific context where the discussion is taking place? I hope that makes sense.
