I know I can say: My hobby is swimming. But when I'm told to tell which part of speech "swimming" is, I still doubt whether It's a noun or a verb. My guess is I put a noun after "hobby is".
This problem came from an English learner who asked me to correct their sentence in a forum. Their sentence is:
My hobby is my garden and my flower.
I know, there's something wrong, though, I'm not sure since I'm also a learner. We help each other to correct our mistakes. Although, I would write this way if I were they:
My hobby is gardening and making a flower bouquet.
But I can't explain why. Could you help me to explain which one is better to write? Also, even though I added the possessive "my" in the front of the base noun (I don't know what it's called), isn't it called a noun-phrase, thus still a noun? If my guess were correct, would it be OK to write like the first one?
Thanks in advance!
