DETERMINERS

Determiners signal (“determine”) that a noun will follow.  Unlike adjectives, which also signal that a noun will follow, determiners cannot add the inflectional morphemes -er and -est.  In addition, because they are function words, determiners do not have other forms or synonyms.  Their "meaning" is their function:  to signal that a noun will follow.

The following examples illustrate the difference:

Determiner + noun tea
 

Adjective + noun tea
 

Note that each adjective has a distinct meaning.

In addition, each adjective may add its comparative (-er) and superlative  (-est) form

 

Types of determiners

1.   articles (the hat, a hat, an opera)  

2.  possessive nouns / pronouns (Mary’s hat, her hat)    (more about possessive nouns)

3.  numbers (five hats, eight hats, twenty hats)

4.  indefinite pronouns (each hat ,some hats, both hats  (more about indefinite pronouns)

5.  demonstrative pronouns (that hat, those hats)     (more about demonstrative pronouns)

  

Native speakers of English learn when to use articles with nouns as they learn to speak.

However, learning when to use articles is often difficult for non-native speakers.

  

The difference between article use with town and city illustrates the difficulty:

   

    Correct:  I walked to the town. (article the before town)

    Correct:  I walked to town. (no article before town)

    

    Correct:  I walked to the city. (article the before city)

    Incorrect:  I walked to city. (no article before city)
