many/much, more, most
few, fewer, fewest
little, less, least

All  quantifiers are  determiners  that express quantity, sometimes exact. But with graded quantifiers we can express approximate quantity on a relative  scale (rising ➚ and falling ➘). (This idea is similar to adjectives  such as big, bigger, biggest or  small, smaller, smallest.) Also note, in the following table, that four of these quantifiers are used with countable nouns (C), four with uncountable nouns (U) and two with both.

many/much

The quantifiers many and much mean "a large quantity of". We use many  with  countable nouns  and much  with  uncountable nouns:

  • Were there many people  at the party? Was it busy?
  • We don't have much time  left so let's go soon.
Note that we tend to use many/much  in negative and question sentences. For positive sentences, especially in informal English, we prefer a lot of, or (very informal) lots of.

-I haven't gotmany eggsmuch rice
?Have you gotmany eggs?much rice?

more, most

Many/much (and few/little ) are unusual determiners because they have comparative   and  superlative forms. The comparative form of many/much is more; and the superlative form of many/much is most. We can use more and most  with countable and uncountable nouns.

Look at these example sentences:

  • Many people use the Internet and more people  join every year.
  • Last year there was a lot of crime, but there is even more crime  this year.
  • Whoever has most points  is the winner.
  • Since you have the most money,  why don't you pay?

few/little

The quantifiers few and little mean "a small quantity of". We use few  with countable nouns and little  with uncountable nouns:

  • There were few people  in the shop so it didn't take long.
  • There is little chance  that he will come now so let's go home.

few/little versus  a few/a little

Notice that few and little  have a "negative" sense:

  • He had few friends . (So he was quite lonely.)
  • We have little  time left. (Just a couple of minutes. Let's go!)

Adding the indefinite article a changes the emphasis to more "positive":

  • He had a few friends . (So he wasn't too lonely.)
  • We have a little time . (A bit of time. Let's grab a snack.)

fewer/fewest, less/least

The comparative form of few is fewer; and the superlative form of few is fewest. We use them with countable nouns:

  • There were few visitors last week but there are even fewer visitors  this week.
  • If Tara has the fewest jobs to do, she can help the others.

The comparative form of little is less; and the superlative form of little is least. We use them with uncountable nouns:

  • The run took little time last week and even less time  this week.
  • Eric has the least work to do so he can help you.
Although less  is correctly used with uncountable nouns only, many native speakers now also use it with countable nouns, especially in informal English:
  • Less people came this time.
Don’t confuse the determiner/quantifier little  with the adjective little  (meaning "small"), which can be used with countable nouns:
determinerThere is little time left.
adjectiveI have a little dog.
