A. Intensifiers: We use words like very, really and extremely to make adjectives stronger. Other intensifiers are: amazingly, exceptionally, incredibly, remarkably, particularly, unusually, etc.
A1. We also use enough to say more about an adjective, but enough comes after its adjective.
B. Intensifiers with strong adjectives
B1. Strong adjectives are words like: enormous, huge = very big; tiny = very small; brilliant = very clever; awful, terrible, disgusting, dreadful = very bad; certain = very sure; excellent, perfect, ideal, wonderful, splendid = very good; delicious = very tasty
B2. We do not normally use very with these adjectives. We do not say something is ‘very enormous’ or someone is ‘very brilliant’.
B3. With strong adjectives, we normally use intensifiers like: absolutely, completely, totally, utterly, really, exceptionally, particularly, quite
C. Adjectives as intensifiers: absolute, total (complete), utter (perfect, real)
C1. We can say: He’s a complete idiot. They were talking utter nonsense. But we do not say: The idiot was complete. The nonsense they were talking was utter.
