The meanings of a word are the uses to which people put it. As such, most words have multiple meanings, and these meanings can differ from person to person. Furthermore, there is no "correct" usage, at least according to my friend who writes dictionaries, as people can use words in any way they'd like. If enough native speakers use a word in a certain way, dictionaries will be updated to include that meaning.
In spite of these different meanings, there needs to be some common understanding, or communication wouldn't get very far. In any case, the meanings of words aren't clearly defined or set in stone. As Wittgenstein would have said, they don't have definitions but rather family relations of definitions, some of which have no direct connection to each other. So 'art' can mean 'deep understanding' (the classical Greek definition), or a knack, or an object made purely for aesthetic enjoyment, or ... It's meanings are legion.
My advice is to stop worring about it, do what you like, and let the salespeople worry about categorization.

Sounds good to me.
As far as I can tell ... "Art" as I know it - or don't know it - is undefinable.
I remember long discussions over the exact composition of light - "particle" or "wave"; electricity; hah! "gravity - all more of less concrete and nowhere as "vaporous" as life, love, aesthetics - joy, ... or any number of human emotions.
Possiblly, wrestling with "electricity" is an exercise providing a useful guide: no one KNOWS what the hell it is; most will concede that is DOES exist; we can use it by predicting its effect ... I don't know what it is, but if I flip this little lever on the wall, something else that I cannot define - light - will happen.
So - back to "art". Whatever it is, I enjoy doing it more than not doing it. Occcasionally I'll discover someone - I describe them as "Kindred Souls" who experience the works - whatever they are - with the same emotional effect as I have.
I'll still wonder about "what it is" - but I would much rather "do" than let that wonder hold me back.
I am not in a position to define it but in one of Joseph Campbells books, I can't remember the title, it give a very enlightening definition. He takes most of his definition from Joyce's book "Portrait of an Artist as a young man". If I can recall the title I'll post it as it is quite interesting and inspiring.
No escaping it!
I must step on fallen leaves
