Example: The trip I took last summer seemed extremely long to me. Example: Our team was absolutely exhausted after the four-day trail. The adverbs really, fairly, pretty and quite can often be used with gradable and non-gradable adjectives. They cannot vary in intensity or grade because they are already at their limit. They can be used with grading adverbs (a little, extremely, fairly, hugely, immensely, intensely, rather, reasonably, slightly, unusually, very, etc.) They can only be used with non-grading adverbs (absolutely, utterly, completely, totally, etc.) They can have comparative and superlative forms. Example: It was freezing in Iceland. The adverbs really, fairly, pretty and quite can often be used with gradable and non-gradable adjectives. They are often used alone. They can vary in intensity or grade (for example you can be a bit cold, very cold or extremely cold). Example: The city tour was more exciting than we expected. Example: During the trip, we hadn’t eaten all day and we were starving.
