We usually use the for nouns (or words that act as nouns) that are specific/known.
The movie (we watched).
Here the refers to the nouns boy & movie respectively. But what about the situation where there an adjective is between the definite article and the noun, like:
The nice boy.
The interesting movie.
Here, to what word does the definite article refer, to boy or nice or the construct nice boy, and to interesting or movie or both?
That is, I meant, what word is specific/known in these sentences that we used the definite article for them?
