Classifying things

Using adjectives to classify

Certain adjectives have the function of classifying things, ie putting them into groups or categories. They answer the question: ‘What type?’ From a functional perspective, we call these adjectives Classifiers.

We can classify things in a number of different ways, including:

Physical location the northern cities
the front door
the underground railway
Composition a plastic cup
a wooden chair
a woollen jumper
Gender a female singer
a male horse

Scientific properties 

an electric shock
a nuclear explosion
a chemical experiment

Group membership

the communist party
a private school
the scientific community
the canine group

One way of telling if an adjective is a Classifier, is to see whether you can put very in front of it. If you can’t, then it is usually a Classifier:

a very plastic cup
a very electric shock

Classifiers are often found in text types where it is important to classify. In general descriptions, for example, we organise the world around us by putting things into classes and subclasses. To do this, we often use classifying adjectives, eg:

Snakes can be divided into two groups: poisonous snakes and non-poisonous snakes. …

The function of classifying can be carried out by other grammatical categories such as nouns (a wine glass, a birthday party) and verbs (scrambled eggs).
