It can be very hard to understand which nouns are abstract and which are concrete.
Concrete nouns are easy. Just like the concrete we use to make buildings and roads we think of them as solid and strong.
Concrete nouns are things you can:
see (a sunset) ,
hear (a song),
touch (an icicle),
smell (a fart)
or taste (honey).
Abstract nouns are things you can’t see, hear, touch, smell or taste.
They are ideas or concepts (time, money, freedom),
actions (running, drinking, falling)
and feelings (hatred, love, confusion).
Abstract nouns are uncountable.
Money is a concept. Dollars, Won and Yen are concrete things that represent money to people.
“I have money.”
“I have 10 dollars”
Time is an idea. Hours, days and years are measurable, real nouns that represent time to people.
“Do you have time this weekend?”
“Do you have a couple of free hours this weekend?”
Some words can be both abstract and concrete, but the meanings change.
“I love you.” love is a concept or feeling.
“I left my love overseas” here ‘love’ refers to an actual person = the person that I love.
“I don’t have time.” time is a concept
“That happened two times.” here ‘times’ is a completely different word, = the number of occurrences.
“I hate winter.” all winters, the concept of winter.
“I went to Europe two summers ago” we are counting a year’s summer as a period of time, not as an abstract concept.
I don’t expect you to master abstract nouns with a short audio clip. I just want you to try to start noticing them more. Mastery (an abstract quality) will come later.
