A meaning of a noun in English may be both countable & uncountable.
fruit [countable, uncountable]: something that grows on a plant, tree, or bush, can be eaten as a food, contains seeds or a stone, and is usually sweet
Fruit is usually uncountable:
I love fruit.
✗Don’t say: I love fruits.
• Fruit is used as a countable noun when talking about particular types of fruit:
They grow mainly citrus fruits.
Some abstract nouns can be used uncountably or countably. The uncountable use has a more general meaning. The countable use has a more particular meaning.
Nouns of this type include: education, experience, hatred, help, knowledge, life, love, sleep, time, understanding.
For example, when "fruit" is a countable noun, it is more specific "My favorite fruits are apples & oranges" (I am not sure it is correct??? Maybe, "My favorite fruits are apple & orange")
& when "fruit" is an uncountable noun, it is more general "I love fruit" or "fruit is good for health"
However, look at the word "sport".
For British people, "Sport" can be both countable & uncountable nouns
So, British people will say "I love sport" (general reference) & "Football & basketball are my favorite sports" (specific reference)
However, for American, "Sport" can be a countable noun only. So, American people would say "I love sports" (general reference) & "Football & basketball are my favorite sports" (specific reference)
To sum up, my question is that does the following statement correct?
"If a meaning of a noun are both countable & uncountable, then its uncountable meaning refers to a more general reference & its countable meaning refers to a more specific reference"
