Remember that we use "a" in front of a word that begins with a consonant
sound even if the first letter is a vowel for example "a piece, a university, a
European language". We use "an" in front of a word that begins with a vowel
sound even if the first letter is a consonant for example "an exercise, an idea,
an honest man".

can use "a" or "an" with nouns that refer to whole numbers, fractions, money,
weights, or measures.
6. We do not use "a" or "an" with uncount nouns or plural
count nouns. We do not need to use a determiner at all with plural count nouns,
but we can use the determiners "any", "a few", "many", "several", or

Many adults don't listen to children.
I have some children like that in my class.
Note that if we do not use a determiner with a plural count noun, we are
often making a general statement about people or things of that type. For
example, if you say "I love dogs" you mean all dogs. However, if you say "There
are eggs in the kitchen" you mean there are some eggs. If you do use a
determiner, you mean a number of people or things but not all of them, without
saying exactly how many.

He has bought some plants for the house.
I have some important things to tell them.
