Sure.

Those weren't four different tenses, but four different names for a tense (which is really an aspect; but I digress.)

"I run." Present indicative.
"I am running." Present progressive. (Also called: present continuous, continuous present, and progressive present.)

Gerund: "Running is fun."
Participle: "I saw a running man."
Intensity: "He is always running!"
Also: "When you called yesterday I was running." Past progressive.


This stuff isn't important. It's just a way of trying to analyze inflection, which is the way we change words to change meaning. In English we don't inflect a lot. But in other languages they do, and the ING is very confusing. It's too versatile.

For an example, I'll choose a nonsense word: scunching.

I scunched yesterday.
I saw a man scunching yesterday.
I saw a scunching man yesterday.
I scunching saw a man yesterday.

Or: I scunching saw a scunching man scunching scunching yesterday.

Scuncher!

I am so scunched.
