We also use the definite article:
• to say something about all the things referred to by a noun:
The wolf is not really a dangerous animal (= Wolves are not really dangerous animals)
The kangaroo is found only in Australia (= Kangaroos are found only in Australia)
The heart pumps blood around the body. (= Hearts pump blood around bodies)
My question is that
In its basic sense, "the" refers to things that are specific.
For example, I don't like the bird (we are talking about that specific bird - the one that I know)
However, "The" is also used to refer to "all things in general".
For example, The bird can sing.
So, when I say "I don't like the bird", do I mean "I don't like birds in general"?
"The" is very ambiguous, in this case.
So, When shouldn't we use "the" to refer to "all the things" in general?
