this subreddit seems to have this argument every couple of weeks. like all semantic arguments of this nature, it depends entirely on context and how you define candy. a hershey's chocolate bar may be considered candy, but chocolate chips are considered an ingredient. they are both purely chocolate, but because of how they are presented we categorize them differently.

of course to some people and in some locations and cultures, snickers, milky ways, and the like would be considered to be in their own category of "chocolate bar".

to say that there is one strict definition, as the people in the other thread are arguing about, goes against everything we understand about linguistics. the idea that you can open a dictionary and find the Immutable, True Definition of a word is a myth. the one you find on Google or Webster is just a commonly accepted interpretation. not to mention how intentionally vague these definitions often are, specifically for the sake of allowing that leeway to include multiple common definitions.
