Wear put on
Hello.
I would like to ask you a question.

Please let me know these sentence's diffrence.

•I am putting on a coat.

•I put on a coat

•I am wearing a coat

•I wear a coat

Answer

Clearly, if you "wear a coat" then the coat is touching your body.

If you "put on a coat", the coat is not touching your body at first, but then it is touching your body.

For the difference between "I (verb)" and "I am (verb)ing", then you need to look at "present simple" and "present continuous" grammar.
