Countable nouns are usually concrete nouns and they can be counted, e.g. a table, three tables.
Uncountable nouns cannot be counted.
We normally do not add ‘a/an’ to them and do not make them plural.

Countable – ‘an item that we drink from which is made of glass’

b) To refer to a specific example of an uncountable noun we can use a bit/a piece , an item , a slice, a lump of:
A bit/a piece of advice, gossip etc.:
An item of news, furniture, clothing
A slice of bread, meat, butter
A lump of sugar
c) In some cases we can make an uncountable noun countable when we want to express ‘different types’ of the noun:
The wines of Provence are incomparable!
d) We can make uncountable abstract nouns countable if we refer to a specific type of the noun:
Distrust -> a deep distrust
This is common with nouns connected with emotions, only in sg form:
Gratitude is a noble feeling.
I felt a deep gratitude to her.
Some uncountable nouns end in –s but take a singular verb, such as
– illnesses (measles, mumps),
– kinds of sport (aerobics, gymnastics)
– academic subjects (mathematics, physics):
– other (news, gallows, summons, optics, ethics, politics )
E.g. Mumps is a disease, especially of children, that causes painful swellings at the sides of the face and under the ears.
Mathematics is my favourite subject.
Collective nouns + singular/plural verb
We can use either a singular or a plural verb with most collective nouns, i.e. nouns referring to a group of people, animals or things.
Army, association, audience, band, board, class, clergy, club, college, commission, committee, community, company, (the) Congress, crew, crowd, delegation, department, electorate, the elite, enemy, family, federation, generation, government, group, institute, jury, opposition, orchestra, Parliament, population, press, public, staff, team, university etc.
+ organizations, companies, e.g. the United Nations, IBM
A singular verb presents the collective noun as a ‘whole’ entity:
The audience was huge.
A plural verb presents the noun as a group of individuals:
The audience were applauding with admiration.
a) Nouns cattle, police always take a plural verb!
b) In formal contexts, academic writing it is common to use a singular verb.
c) US English prefers a singular verb in these cases.
d) It is preferable to use a singular verb after a collective noun if we use a/an rather than the:
A group of teenagers is dancing in the street.
