Gradable and non-gradable adjectives
Most adjectives are gradable. This means that their meaning can be modified (made stronger, weaker, or otherwise altered) by placing one or more adverbs in front of them. For example:
an expensive car
a very expensive car
a fairly expensive car
an extremely expensive car
The adverbs very, fairly, and extremely are telling us where this particular car belongs on the scale of ‘expensiveness’. By using them, we can make a significant difference to the meaning of an adjective.
Non-gradable adjectives are those with meanings which cannot be modified by adverbs. For example:
the western side of the mountain
a nuclear reactor
It would be very strange to see any of the adjectives in the above examples being used with modifying adverbs such as very, fairly, or extremely; things are either western, electronic, or nuclear, or they’re not. These sorts of adjectives are part of the category known as classifying adjectives.
