We use words like very, really and extremely to make adjectives stronger:

It’s a very interesting story

Everyone was very excited.

It’s a really interesting story.

Everyone was extremely excited

We call these words intensifiers. Other intensifiers are:

amazingly
exceptionally
incredibly
particularly
remarkably
unusually

We also use enough to say more about an adjective, but enough comes after its adjective:

If you are seventeen you are old enough to drive a car.

I can’t wear those shoes. They’re not big enough.

Strong adjectives are words like:

very big enormous, huge
very small tiny

We do not normally use very with these adjectives. We do not say something is very enormous or someone is very brilliant

With strong adjectives, we normally use intensifiers like:

absolutely
completely
exceptionally
particularly
really
quite
totally
utterly

The film was absolutely awful.
