Is of an article?
The word “of” is not an article but rather, a preposition. As a preposition, “of” begins a prepositional phrase, which also includes a noun. The following examples include prepositional phrases (in bold) that begin with “of.”
- The pyramids are made of limestone blocks.
- Michael published a book of poems.
In contrast to a preposition, an article is a determiner that modifies a noun. The definite article in English is “the,” and the indefinite articles are “a” and “an.”
