Still acting [like] a child, I see.

Hi, Is it correct to say, "Still acting a child, I see".

Hi there, and welcome to the forum.
No. The sentence you asked about is not right; in particular, the "a" in it is wrong. It should be "the".
By the way, is the info on your profile correct?

Hi.

Is it correct to say no comma here "Still acting a child, I see"?

No. It would be either "Still acting the child, I see" or "Still acting like a child, I see". There's an implied "You're" at the start.

Perhaps:

I see you're still acting like a child.

Of course, you shouldn't expect a good reaction.

In what context do you want to use this sentence, @oyediranabdurrahman?
