There are two primary indefinite articles in English, ‘A’ and ‘An’. Their use depends on the first letter of the following word that comes after the article. This to make pronunciation easier. You should use ‘a’ when the next word starts with a consonant or variation of the word that makes it sound like a consonant. You should use ‘an’ when the following word starts with a vowel or a silent consonant that makes it sound like it starts with a vowel.

Distributive determiners are used to refer to a group of people, things, or ideas. They are also used to refer to individuals among a group.

These distributives can only be used with countable nouns. ‘Each’ expresses the individuality of a member in a group. ‘Every’ expresses the series of members within a group.

Each’ can be used with plural nouns when followed up with ‘of’. ‘Every’ CANNOT be used with plurals.

Using ‘All’ as a distributive – Whole Group

All’ as a distributive is used to refer to an entire group. It focuses on the idea that the whole group is complete and has nothing left out.  They can be used with uncountable nouns and plural nouns on its own. However, it refers to the group as a figurative concept rather than as a literal example.

  • All fruits are healthy for us.

All’ can be used with plural pronouns or possessive pronouns if it has ‘of’ before the noun.

  • All of us are going to the party, why won’t you?
  • Stop taking all of her stuff!

All’ can also be used with uncountable nouns when accompanied with ‘the’, ‘this’, or ‘that’ during a question or an exclamation. However, with countable nouns, you’ll want to use ‘these’ or ‘those’. You may also add ‘of’if you choose to (doesn’t change the meaning).

  • What’s with all the commotion here?
  • Where did all this stuff come from?
  • Why did you throw away all of that food?
  • Take a look at all those trees!

Using ‘Half’ or other fractions as a distributive – Dividing a Group

Half’ as a distributive is used to refer to a whole group split in two. Other fractions such as ‘Quarter’ may also be used. There are several patterns on how fractions can be applied with ‘Half’ being the most common. The first use for ‘Half’ is with measurements when preceded by an indefinite article such as ‘a’ or ‘an’. You’ll have to use ‘of’ when pairing up with another fraction such as ‘Quarter’.

  • I drank half a bottle of juice.
  • He is half an inch taller than me.
  • He filled up the tub with quarter of a gallon of water.

Half’ can also accompany nouns preceded with a definite article (the), a, another demonstrative, or a possessive adjective. This will refer to n actual physical division. ‘of’ can also be added with no change to the meaning.

You may also use ‘Half’ with plural pronouns by accompanying it with ‘of’.

Using ‘Both’ to pair objects

‘Both’ is used to equally refer to a pair of two as a whole. It can be used with plural nouns on its own, or it can be accompanied with ‘of’, along with or without an article. ‘Both’ cannot be used to refer to singular nouns as it refers to two things. Plural pronouns require ‘of’ to separate itself with ‘Both’.

  • Both students were successful in school.
  • Both the students were successful in school.
  • Both of the students were successful in school.
  • Both of them were successful in school.

Using ‘Either’ to positively distinguish one or another in a pair

Either’ means ‘one or the other’ within a pair. It refers to one of two parts in a pair and must be used with a singular noun. However, it may also be used with plural nouns or pronouns when followed up with ‘of’.

  • I can eat at either restaurant.
  • Either of them could have won the race.

Either’ can function like a conjunction when paired with ‘or’ to talk about each member of a pair. In this type of sentence, ‘either’ doesn’t function as a distributive.

  • They will either play at an arcade or watch a movie for their date.

Using ‘Neither’ negatively distinguish one or another in a pair

Neither’ functions similar to ‘Either’ as it means ‘one or the other’ within a pair but is used as a negative. ‘Neither’ must be used with a singular noun and can also be used with plural nouns or pronouns if followed up with ‘of’.

  • Neither men are hard working.
  • Neither of us could have figured out the answer to the puzzle.

Neither’ can function like a conjunction when paired with ‘nor’ to talk about each member of a pair. In this type of sentence, ‘neither’ doesn’t function as a distributive.

  • We will neither play nor watch soccer.

Difference Words: When to use ‘Other’ or ‘Another’

The determiners of difference, ‘Other’ or ‘Another’ refer to something different, remaining, or additional. They normally precede nouns or adjectives that describe the nouns. However, ‘the other’ works differently from the two.

Using ‘Other’ with plural countable nouns and all uncountable nouns

Other’ can be used alone or when combined with other determiners like some, any, or no.

  • Do you need help from other people?
  • You could complete your task any other way.
  • He must know some other doctors who can help.
  • There is no other strategy better than mine!

In the case where the plural countable noun is understood from context, it may be omitted and ‘other’ can take its place as a plural.

  • Some others have worked very hard to do well in their exam.
  • There are no others willing to take the challenge.

Using ‘Another’ with singular countable nouns

Another’ is used with singular countable nouns but can also be used with uncountable nouns if used with a word that can measure the uncountable noun.

  • I have another present for you.
  • You can add another bag of sugar to the shopping cart.

Using ‘The other’ with any noun that meets the criteria of the definite article

‘The other’ can be used to modify plural countable nouns. The noun can be completely omitted if understood from context, which ‘the others’ will become a plural itself.

  • I can’t find the other pencil that’s missing!
  • My friend won one game out of 10. I won the others.

How to use Pre-determiners

Pre-determiners express an opinion about the noun that is they modify. Words like ‘Such’ or ‘What’ are placed before an indefinite article + adjective + noun to express emotions.

  • Such a horrible night we had!
  • What a wonderful thing to say!

Rather’ and ‘Quite’ can display pleasure, disappointment or other types of emotions depending on how it is used.

  • That was rather a nice meal.
  • He was quite a tall man.
  • That was rather a weak display of showmanship.


Quantifiers are adjectives and adjective phrases that give indirect or direct answers to questions that ask for quantity. They are also determiners that function to make the noun clearer.

Cardinal and Ordinal Numbers

Number Cardinal Ordinal
1 one first
2 two second
3 three third
4 four fourth
5 five fifth
6 six sixth
7 seven seventh
8 eight eighth

How to read decimals

When expressing decimals vocally, you would say ‘point’ for the decimal point. For example, you would say ‘zero point five’ when reading ‘0.5’. You would say ‘fifteen point three nine five eight’ when reading ’15.3958’.

How to read fractions

Read aloud using cardinal numbers for numerators and ordinal numbers for denominators. However, if the denominator is 2, you’ll have to read it out as ‘half’ if its lower than 2, and ‘halves’ if it is than 2.

You may also choose to use ‘quarter’ if the denominator is 4. For example, ‘one fifth’ would be used to describe ‘1/5’ and ‘one half’ would be used to describe ‘1/2’.

However, ‘four halves’ would be used to describe ‘4/2’. You may also say ‘one quarter’ to describe ‘1/4’.

How to read percentages

You may read the number in its cardinal form along with the word ‘percent’. For example ‘thirty-five percent’ as ‘35%’

How to read money

Reading money aloud is simple as reading the whole number along with the currency. Follow the decimal rule if it includes a decimal. For example, ‘five dollars’ would be used to describe ‘$5’.

How to read measurements

Read out the whole number along with the unit of measurement. For example, ‘twenty-five milliliters’ for ‘25mL’. You may apply the decimal rules before pronouncing the unit of measurement.

How to read years

Reading years could be a bit complicated as there are numerous ways to do it. However, the more common way to pronounce years in four digits would be to read the first two digits as whole numbers and the last two digits as separate whole numbers.

For example, ‘twenty nineteen’ would refer to ‘2019’. However, you may also just read it as a whole number, ‘two thousand nineteen’.

If you have a three-digit number, you may either read it as a complete whole number or read the first digit as a whole number separate from the last two digits that can also be read as a whole number.

For example, ‘nine fifty-seven’ for ‘957’ or just ‘nine hundred fifty-seven’.

How to pick the proper quantifier

While some quantifiers can be used with countable nouns, others can be used with uncountable nouns. These are normally used to answer questions that ask about quantity or volume.

Only with uncountable nouns With all types of nouns Only with countable nouns
a little no, none, not any a few
a bit of some a number of
  any several
a great deal of a lot of, lots of a great number of
a large/huge/enormous amount of plenty of a large/huge/enormous number of

How to use ‘much’ and ‘many’

‘Much’ and ‘many’ are mostly used in interrogative questions. ‘Much’ is used for uncountable nouns whereas ‘many’ would be used with countable nouns. For affirmative sentences, they are used with ‘too’ and ‘so’. ‘Many’ can be used alone in affirmative sentences whereas ‘much’ cannot.

Note: ‘A lot’ or ‘lots’ can replace both ‘much’ and ‘many’ in affirmative sentences.

  • How much water can you drink?
  • How many people can sing as good as you?
  • I ate too much chicken last night.
  • Not a lot of people showed up last night.

How to express opinions about quantity in a positive way (humble) or negative way (ungrateful)

‘a few’ and ‘a little’ can be used to describe a quantity that seems either sufficient or positive. ‘Few’ and ‘little’ can describe the quantity to be lacking or negative.

  • I have a few change in my pocket. (Can imply that the speaker can spare some)
  • I have few change in my pocket. (Can imply that the speaker doesn’t want to spare anything)

Using ‘Some’ or ‘Any’ to describe Indefinite and incomplete quantities

‘Some’ can be used for a variety of different sentences. Such as descriptive sentences, interrogative sentences where may already know the answer, or interrogative sentences where you ask for something or offer something.

  • I ate some fruit
  • Did you eat some fruit?
  • Could you give me some fruit?
  • Would you like some fruit?

You may use ‘Any’ in interrogative sentences when you do not know the answer or with not to make a negative sentence that emphasizes the negativity. It could also be used as a rhetorical question to prove a point.

  • Do you have any female friends you can introduce me to?
  • No, I don’t have any female friends to introduce you to.
  • Do you have any idea how hard it is to meet a girl?

Using graded quantifiers to compare amounts

Graded quantifiers allow comparison between different quantities. Countable and uncountable nouns require different quantifiers. In some cases, the noun could be absent if it is understood from context.

Quantifier Comparative grade Superlative grade
With plural countable nouns
many more most
few fewer fewest
With uncountable nouns
much more most
little less least

Using ‘Enough’ as a quantifier

You may use ‘Enough’ as a quantifier to indicate that the quantity is sufficient or necessary. It can also be used as an adverb, which doesn’t require it to be paired with a noun.

  • There are enough people here to build a train.
  • I don’t have enough money to buy that toy.
