Many nouns, especially singular forms of countable nouns, must have an article.
In English, it is not possible to say I sat on chair
without an article,
but a demonstrative or possessive adjective can be used
instead of an article as in the sentences I sat on that chair
and I sat on his chair.
Whenever you see an article, you will find a noun with it. The noun may be the next
word as in the man
or there may be adjectives and perhaps
adverbs between the article and the noun as in the
very angry, young man.
