Mr. Beeesneees,
Are the answers of Mr. Ruifeng correct.
Please comment.

Yes, they are.

Mr. Beeesneees,
instead of saying “He’s kind of sarcastic.”
can I say: “He’s a kind of sarcastic” ?
Which is better?
For “What kind of flower is this ?”
can I say: “What a kind of flower is this ?”
Please comment

No you cannot use the article in either of those sentences

Mr. beeesneees,
I have seen the following sentence somewhere in the web.
“It is a kind of dog.”
Is it wrong?


‘A kind of dog’ suggests ‘similar to what a dog looks like’ and is acceptable. ‘He’s kind of sarcastic’ suggests ‘He’s a little bit sarcastic’.


No, that is not wrong.
The difference is that ‘dog’ is a noun. ‘Sarcastic’, which you chose to use in your example statement, is an adjective.
In your second sentence about the flower, the article is misplaced. The word order changes in a question.

It is a kind of .
What kind of a is this?


To develop what I said above, ‘kind of’ (in contrast to ‘a kind of’) suggests ‘to a certain extent’. This can be used both with an adjective or a noun as in: He’s kind of foolish/He’s kind of a fool.
