Word classes in English grammar

The verb

A group of words cannot be described as a sentence or a clause unless at least one of the words is a verb. In some ways, we can describe it as the most important part of speech because it is the ‘action’ word that tells the listener or reader what is happening in the sentence. Verbs can be ‘action’ words like run, initiate, judge, throw, but they can also denote less active notions and have more to do with mental processes and perceptions, like see, know, think and so on.

The noun

A noun is a word which is used to denote a person (traffic warden, woman, Prime Minister, pianistetc.), a concrete or abstract entity (binoculars, fork, field, truth, incoherence etc.) or a place (office, garden, railway station). These are all common nouns; there are also proper nounswhich are the names of a specific person, place, event etc., usually starting with a capital letter, for example, York , John, Christmas, Saturday.

A noun can be extended to a noun phrase. In the example phrases given below, the noun (in the first example) and the noun phrase (in the remaining examples) is in bold. Note how much the noun phrase can be extended by adding extra information each time.

Dogs can be vicious

Some dogs can be vicious

Some of the dogs can be vicious

Some of the bigger dogs can be vicious

Some of the bigger dogs in the dog pound can be vicious

The adverb

The traditional approach to adverbs has been to assign mainly those words which are made from adjectives by the addition of the ending –ly (quickly, hopelessly), plus certain other words which are difficult to classify, like not, just and soon. Their main function is to qualify the action of the verb in the clause in some way, but they can also be used to add more information to an adjective or other adverb e.g. awfully good, incredibly slowly. The class of adverbs is very wide-ranging in form and is used to add comments to many of the other word classes.

The preposition

Prepositions allow us to talk about the way in which two parts of a sentence are related to each other. They include words like in, on, under, beside, through, inside, before, opposite. More often than not, these relationships are to do with either time or space, but other types of relationship, such as possession, cause and effect and method can be expressed by using prepositions. The words themselves are generally short and simple but some prepositions are multi-word units; for example, out of, by means of, in spite of, instead of, up to etc. Unless they are part of a verb (getin, pick up, switch off), prepositions are always followed by a phrase containing a noun – at school, in the summer, over the moon and so on.

The adjective

An adjective gives the reader or speaker extra information about a noun or delimits it in some way. It can occur in two positions in a phrase:

  • before the noun as in clear water, beautiful beaches, a terrible decision. The adjectives in these examples are said to be attributive,
  • following any form of the verb be (e.g. am, is, was, been) and similar verbs (seem, appear,become) as in the water became clear, the beaches are beautiful. These adjectives are inpredicative position.

The pronoun

Pronouns are usually treated as a special sub-class of nouns. This is because they stand in for a noun or group of nouns. They are limited in number and belong to what is called a closed set, that is, a group of words to which new members are, for practical purposes, not allowed. Some examples of pronouns are: I, you, he, she, our, its, something, anyone and so on. Thus, instead of saying, Bill’s arrived. Bill’s in the lounge, we prefer Bill’s arrived. He’s in the lounge. Or a person called for you; better would be someone called for you. There are several other words which fall into this class; for example (the) one(s), when used to replace dishes in the example: pass me the dishes – the ones on the top shelf.

The conjunction

It would be very unusual for anyone to either speak or write completely in simple sentences; instead we tend to use a mixture of simple, compound and complex sentences. One way to create longer, more complicated sentences is to use conjunctions. As we have already noted in the section on types of clause, conjunctions serve to connect two or more clauses, phrases or words together to make longer constructions. In the following examples, the conjunction is in bold:

  • The coffee was strong, but sweet.
  • We can go to the match or watch it on TV.
  • She has a dog and two cats.
  • When I arrived home, they had already eaten.
  • I had to stop driving because the rain was so bad.
  • Can I have a word with you, if you’ve got the time?
  • Although he can’t swim, he goes sailing.

There are two types of conjunction. The first is the coordinating conjunction; examples of this can be seen in sentences a to c above. This type is always used to connect elements that share the same grammatical status, that is, main clause to main clause, verb to verb, noun to noun, adjective to adjective and so on. In sentence a two adjectives, strong and sweet, are conjoined, in b two verbs, go and watch and c two nouns, dog and cats.

The second type is the subordinating conjunction, which most often joins two or more unequal clauses to one another. Typically a main clause will be connected to a subordinate clause as we saw in the section on clause types. So in sentences d to g above, the subordinate clause (which you will remember cannot stand on its own, but needs another more important clause to complete the meaning) begins with a conjunction, here when, because, if and although.

Word class membership

Although the description above may give the impression that any one word within a single meaning belongs exclusively to one word class, you should note that this is not the case. Study the words in bold in the following examples:

  • I couldn’t give her an immediate answer .
  • I was surprised when he answered my letter.
  • Do not write on the front of the answer sheet.
  • In the first sentence, answer is being used as a noun – note the attributive adjectiveimmediate and the word an, both indicative of a following noun.
  • In the second, answer is a verb – the subject he and the ending –ed­ show this.
  • While in the third, answer tells you what kind of sheet is being talked about and is, therefore, an adjective.

This flexibility in word class membership is a peculiar feature of English among the European languages, many of which would require different endings to show the class of the word.
